Absolute Magnitude Luminates Absolutely

This week I want to discuss “What might cause the closer of two identical stars to appear dimmer than the farther one?”

Apparent Magnitude: A measurement of the brightness of stars without regard to their distance from Earth.

  • The scale in use today starts with the star Vega and an apparent magnitude of 0.0
  • Objects brighter than Vega are assigned negative numbers.  For example. Sirius, the night’s brightest star, has an apparent magnitude of -1.44
  • The scale was extended to include the dimmest stars visible through binoculars and telescopes.  For example, a pair of binoculars can see stars with an apparent magnitude of +10

Ignoring distance for a moment, all other things being equal, the closer of two identical stars will appear brighter (have a smaller apparent magnitude) to us than the more distant star.  When we account for the difference in distance, we use either or two measurements:  absolute magnitude and luminosity.

Absolute Magnitude: The brightness a star would have at a distance of ten parsecs (10 pc) or 32.6 ly. Continue reading “Absolute Magnitude Luminates Absolutely”

Backyard Observing

20161021_175740
Friday evening setup: tarp (to catch falling bits and pieces in the dark) and the base.

All last week, I looked forward to the weekend as a chance to get some astronomical observing accomplished. The weather forecast seemed too good to be true: Sunny and clear, highs in the mid 70s and lows in the 50s, with dew points in the upper 40s and lower 50s. My astronomy club hosted a club star party, but I did not want to lug the scope to Louisburg and share the observing grounds with a previously scheduled private party.

Autumn Arrives and Adventures in Astronomical Observing

Autumn arrived mid-week here in the Heart of America, but you wouldn’t have known it by looking at the weather forecast:  Mid 90s and moderately high humidity.  Also with the change of the seasons, I retired my FitBit Charge (or rather it retired itself by falling apart) and upgraded to a Samsung Gear Fit2.  The new fitness tracker is spurring me on to be more active, although my sleep pattern hasn’t improved much. I can safely blame work (10 pm to 4 am conference call on a Saturday night/Sunday morning) and astronomy, which requires, well, dark skies, for my reduced snooze time.

Speaking of astronomy, I’ve upgraded, finally after two years of paralysis analysis, from the Meade ETX 90, gifted to me by my father in October 2010 (also, unsurprisingly the birth of this blog site), to an Orion SkyQuest XX14G.  Continue reading “Autumn Arrives and Adventures in Astronomical Observing”

Star Light, Star Bright, May I Count You All Tonight?

I missed the opportunity to count stars over the weekend.  Clouds obscured the heavens Friday and Saturday night, but I had absolutely no excuse not to step outside Sunday evening and participate in the Great World Wide Star Count.  Thank goodness that Sky & Telescope‘s Facebook feed reminded me with their article ‘A Star Count for Everyone‘ this morning.

I checked my local five day forecast and I should be able to find Cygnus and count stars tonight and Wednesday.  Tuesday, Thursday and especially Friday are iffy.  This year, I’m going to try to do it from a couple of different locations, not just my backyard (like I did last year).

Here’s all you need to know to participate:

All you’ll need are a clear evening sky sometime between October 5th and 19th, your own two eyes, and a set of simple star charts. First, download the handy five-page activity guide (available in 16 languages) and print the star charts. If you live in the Northern Hemisphere, you’ll be looking high up for the constellation Cygnus, and its Northern Cross asterism. If you’re south of the equator, the target area surrounds the Teapot in Sagittarius. Each of the seven maps shows stars down to a different magnitude limit, plus one for a cloudy sky.

Then, after stepping out under the early-evening sky and letting your eyes adjust to the darkness, match one of the charts to what you see overhead. Step back inside and report what you’ve found online. You’re done! (Unlike many contests, you can enter more than once! You might be surprised by how much the sky’s darkness can vary from night to night.)

A Star Count for Everyone, Sky & Telescope, Oct. 5, 2012

Fishing for Neptune: Testing the Waters

I couldn’t wait for midnight Friday night.  The forecast for the weekend seemed unbelievable, especially after the scorching heat of the last month.  Clear skies and mid to lower 80s for the high temperatures over the next several days.  I came home from work to a grilled steak and baked potato dinner, prepared by Terry.  Mmm-mmm good.

After dinner, Terry and I began reviewing the DVR play list and guide, deciding to delete many old recordings to free up some disc space.  Our daughter called and chatted with us for about forty-five minutes.  The conversation ended abruptly when her phone battery died.

For dessert, Terry blended a frozen raspberry lemonade.  I read for a few minutes, while slowly sipping the drink (trying to avoid a brain freeze).  I asked him to wake me up around midnight so I could scout the skies in search of the Andromeda galaxy and the planet Neptune. Apollo followed me upstairs to the bedroom to join me in my nap.

Terry woke me up just shortly after midnight.  I rubbed the sleep out of my eyes and found my flip flops.  I followed Terry back downstairs to the band room and walked out the patio door to the back yard.  The skies were clear, if not what you’d call dark (why do my neighbors leave their porch lights on all night long?).  I went back inside for one of my star charts and a pair of binoculars.  I didn’t trust myself to lug the telescope outside in the dark, not being completely awake yet.  A survey with the binoculars should be sufficient for my first attempt.

I walked out into my backyard, towards my one remaining pine tree and turned back around to face the east.  What a difference a couple of hours makes!  I could clearly see the Great Square of Pegasus hovering directly over my roof.  In fact, my chimney seemed to be pointing a finger at the famous flying horse.  I remembered what I’d read in the EarthSky post about finding the Andromeda galaxy and put what I’d learned to good use.  With just a pair of mediocre binoculars, I easily found the smudge that is M31.  Now I regretted not moving the XT8 outside before I took my nap.

I turned ninety degrees to the right and began scanning the southern skies.  I can’t see most of the southern horizon, which is blocked by my neighbors tall trees and houses (and all the exterior lighting attached to them).  I lose a good twenty if not thirty degrees of sky in all but one direction, to the southwest I can see a bit of horizon, but only through the even worse light pollution generated by the parking lot of a doctor’s office and the streetlights along Main Street (also known as K-7/US-73).

I needed to find the constellations Aquarius and Capricornus.  The ecliptic passes through both of these constellations.  Neptune swam the night skies somewhere between the two constellations on the invisible ecliptic course all the planets chart.  The trouble in finding Neptune in this area of the sky comes from a lack of bright stars to anchor from for star hopping.  I spent the next hour comparing the star atlas from my pocket guide to the stars I saw through the binoculars and eventually convinced myself I had found the southeastern tip of Capricornus.  Just above those stars, I believe I found the two brightest stars in Aquarius, Sadalmelik and Sadalsuud, but those two stars were too high above the ecliptic and too far away in the field of view of the binoculars to find Neptune.  I needed to do more research and next time use a telescope to help cut through the fog of light pollution.

After an hour, I returned inside and went back to bed, resolved to research better star charts in the morning.

I went back to Astronomy.com and re-read the article on Neptune, but I just couldn’t relate their star chart (shown above) to what I’d observed last night through the binoculars. I would need more magnification and a more steady mount to zoom in and match up the stars shown above to the field of view of the XT8.

I tried Sky and Telescope’s web page and found a better set of charts in a PDF format in their article about Uranus and Neptune visibility during 2012.  I downloaded the document and will print it today to keep with the rest of my star charts.

Saturdays are always packed full of activities, so I’m hoping I’ll still have the energy tonight to make a second attempt at finding Neptune.  My scouting trip showed me what I needed to overcome before I proceed with netting Neptune.

Friday Night Lights and Monday Highlights

Waning Moon
Waning Moon approaching Jupiter (Fri Aug 10, ’12)

Very early Friday morning, I caught the waning moon approaching Jupiter and Aldebaran. You could draw a line from Venus to Moon and cross over or near Jupiter.  The skies were clear and should stay clear throughout the day and into the night, with a forecasted high in the mid-80s, twenty degrees below what we’ve been experiencing for the past several weeks.

Derek and RoynaFriday at work was a whirlwind of meetings, including one held off site at another local law firm.  I got home a bit early because one of my vanpool riders took the day off, but within fifteen minutes of getting home, my son and daughter-in-law arrived from their all-day road trip from North Texas.  We visited with them for an hour and half, when they left to drive into Kansas City to spend the evening with several of their friends who still live in the area.

Terry cooked an excellent southern comfort food type dinner of chicken-fried minute steaks, organic green beans with turkey bacon, mashed potatoes and home-made white gravy.  Too bad the kids didn’t hang around long enough to chow down with us.  Terry and I let our food digest a bit, watching the Olympics until the skies darkened enough for some star gazing.

I grabbed the XT8 (affectionately known as ‘Dob’) and carefully carried it out to the lower backyard.  This time I took a small table to put my charts on.  I set my case of eyepieces on the ground.  I brought out the Intelliscope handheld device to attempt an alignment.  This device, unlike my ETX-90’s AutoStar, is only used to identify objects, not ‘go to’ them (since the XT8 does not have any motors).  The Intelliscope can help you find objects with a warm/cold kind of seeking system.  I still haven’t bought a stool to lean against, so my back aches a bit this morning.  I did a two star alignment, finding and centering Arcturus first, then Vega.

I wanted to revisit the Double Double in Lyra to both confirm that I could find it by star hopping and to attempt to see the double within the double.  I asked the Intelliscope to ID what I had centered in the eyepiece and it claimed I’d found the Crab Nebula.  Hmmm.  That’s in the constellation Taurus, which isn’t visible until early morning hours in the east.  I must have done something wrong in the alignment process.  I powered off the Intelliscope device and made a note to myself to re-read the manual in the morning.  Since I’d already found Vega, I spent several minutes comparing my star atlas to what I was seeing in the finderscope.  I found Epsilon Lyrae and observed it with 26mm, 15mm, 9mm and a 2x barlow (using the 26mm and 15mm).  Despite the apparent clearness of the skies, I did detect some haziness and thin stratus clouds overhead.  That may have inhibited my ability to split the doubles within the doubles.

I hopped over to Albireo in Cygnus, just to make sure I could find it again without referring to my star atlas.  I used a trick I had read about from some artists who do astronomical sketching where you defocus the stars, especially doubles, to discern their different colors.  I did this while observing Albireo and I could clearly see the red and blue for each star in the double.  I stretched my back for a few minutes and stared off to the northeast, at Cassiopeia, which I could clearly see as a distinctive ‘W’ shape.  I could not see the constellation Perseus, but I did see one or two meteors radiating from the space between Cassiopeia and where Perseus should have been visible (but wasn’t because of the haze and light pollution from the prison just north of my location).

I returned to the scope and began a star hop around Lyra in search of M57, also known as the Ring Nebula.  This was a test, for me, not only of my ability to find this fuzzy smoke ring, but also of an 8-inch telescope’s ability to cut through the obstacles inherent at my closest observing site (my backyard).  I surprised myself.  I found the nebula, quicker than I thought I would, and I even saw it through the finderscope.  It probably helped that Lyra was almost straight up above me and the telescope, meaning I had less atmosphere to peer through.  Using averted vision, with the 9mm, I could clearly see the ring.  I used the background stars to focus, because you can’t really focus well on a smudge that’s fuzzy and faint.

Since I found and saw a nebula with the XT8, I wanted to see if I could find a globular cluster next.  And I just happened to know where one was.  M13 in the ‘armpit’ of Hercules (see chart above) happened to be overhead, somewhere between Altair and Arcturus.  I had some trouble locating the stars that make up Hercules with my naked eye.  I took several minutes, stretching my back, to peer overhead, but towards the west, and Arcturus.  Eventually, the star dots connected in my mind’s eye and I found the constellation.  I oriented the XT8 to the general vicinity where I thought M13 would be.  I think I saw it through the finderscope, although I can’t remember specifically.  Using the 26mm eyepiece, I centered the globular cluster in my field of view and proceeded to observe this large dense cluster for several minutes with various magnifications.

I stared off into the northeast again, still trying to find Perseus and also Pegasus.  If I could see the Andromeda Galaxy (also known as M31), I would achieve a triple crown of astronomical observing from my backyard with the XT8 (1: nebula; 2: globular cluster; 3: galaxy).  I spent nearly a half an hour, roaming around my backyard, changing my point of view and line of sight to the northeast and east.  I found Cepheus, but no matter how hard I squinted or averted my eyes, I could not clearly identify the box that makes up the body of Pegasus.  Frustrated, and with an aching back, I decided to call it a night at about half past eleven o’clock.

I returned the telescope to the band room and replaced all the dust caps.  I hugged my hubby, for he had brought me a refreshing freshly made strawberry lemonade to enjoy while bending over the telescope for hours.  Off to bed and sleep, at least until the dogs started barking when Derek and Royna returned home (sometime after midnight and before five – not exactly sure as I tried to sleep through the commotion).

My alarm only fires off on weekdays, but most days I wake up fifteen minutes early.  Not Saturday morning though.  When I cleared the sleep from my eyes and checked the clock on my cell phone, it read 5:45 a.m. and I could already tell the eastern horizon was brightening.  I grabbed the tripod and camera and went out to the driveway to take a photo of the Moon approaching Jupiter.

Waning Moon Approaching Jupiter
Waning Moon Approaching Jupiter (Sat morning Aug 11, ’12)

If I happened to live in the Pacific, today I would be able to observe the moon occulting Jupiter.  But I won’t be too disappointed, since I can observe the moon occulting Venus next Monday afternoon, between 3:00 and 4:00 p.m.  I plan to take a pair of binoculars and my camera equipment with me to work.  I will setup on the top of the parking garage and hope I have a clear line-of-sight through the buildings to the west to see the occultation as it occurs.

But tonight I plan to find a dark sky location and take in as many meteors as I can, raining down from Perseus.  I better take a nap this afternoon and set an alarm for one o’clock Sunday morning.  Don’t want to miss the best meteor show of the year!

Star Party Sign In
Star Party Sign In (click image for rest of album)

My dad contacted me Thursday to coordinate conveyances for our weekend astronomical adventure, thinking we would be attending the monthly ASKC club meeting, but he was a week early. Since I had mentioned earlier in the week a desire to see the glorious summer spread of our own Milky Way Galaxy, he had called me several times the past few days to see about driving to northern Atchison county to escape the Kansas City area light pollution. Both Wednesday and Thursday evenings turned out to be hazy and cloudy, so we nixed the road trip north.

Instead, I suggested we attend the monthly star party at Powell Observatory.  I received two confirmation e-mails from David Hudgins, the club’s star party coordinator extraordinaire.  I decided to leave my scope at home because you don’t really need a scope to take in the Milky Way Galaxy.  If the skies grew dark enough, it would stretch from the southern horizon, up over the top, clear to the northern one.

I thought perhaps I was reliving last Friday (that would be the 13th) because when I got home early (by ten minutes) I walked into some surreal drama.  I won’t go into the stressful week at work (we’ve all had weeks like that), but I looked forward to forgetting work and ignoring the excessive heat by reading books and watching movies in a quiet, air conditioned home with my hubby and two Rotties.  I came home to find our satellite on the fritz and Terry needing me to pickup a prescription before the pharmacy closed at seven.  While he cooked dinner, I did some preliminary troubleshooting of the satellite system with little success and decided to call DirecTV customer service, knowing I’d probably be on hold for several minutes.  The technician wanted us to disconnect, check and reconnect all of our cables, which seemed a ridiculous request since the cable runs are static and have not been touched, moved or manipulated in years.  After almost ruining supper in an effort to jump through DirecTV tech support hoops, we hung up on them and sat down to eat.

By now, I had less than an hour to pickup the prescription, so I grabbed my purse and drove to the store.  I got as far as the pharmacy counter, where the assistant recognized me and had the prescription ready for me, but when I opened my purse, my billfold was missing.  I had left it in the van because I stopped at Starbucks after work for a mocha frappacino treat for the drive home.  Now I had to return home for my billfold and repeat the trip back to the pharmacy, a wasted trip, time and gas.  When I returned home the third time, Terry had solved the satellite system glich.  With our excessive heat and drought conditions, the ground supporting our satellite dish pole has dried up so far down into the ground, that the pole can now be easily moved back and forth and twisted on it’s concrete base.  One of our dogs could have bumped into it and messed up the alignment.  Terry used the signal strength meter diagnostics channel on the satellite receiver to dial the dish back in.

Hoping that would be the final challenge of the week solved for the moment, I called Dad just after seven o’clock and told him to head my way.  I gathered up my camera equipment, my pocket star atlas, a large hardcover edition of Backyard Astronomy (to review Milky Way info), my purse (with billfold) and a lidded glass of cool water.  I asked Dad to drive this weekend, volunteering to drive next weekend for the July club meeting.  The hour jaunt to Louisburg passed quickly and we arrived at Powell just moments after sunset.  The evening cooled off nicely, but remained calm, clear and surprisingly dry.  In fact, we experienced no dew (the bane of telescope optics) until after midnight.

Sterling Scope

Several club members were already present and setting up their scopes in the East Observing Field (click photo above for photos taken upon our arrival).  One member, Mike Sterling, introduced himself to me (asking if I was ‘the’ Jon Moss … apparently my name is known, if not my face or gender, from my blogging).  He was in the process of collimating his 20-inch Dobsonian.  My dad provided an extra pair of eyes to help finish.  Mike also gave us a color brochure published by Astronomy magazine of the illustrated Messier catalog.  This will come in handy in the future when I really get serious about an observing award.

Star Party Theme: Star Charts
Star Party Theme: Star Charts/Atlases

The theme for this month’s star party centered around star charts and atlases.  David Hudgins setup a table displaying several popular and easy-to-use books, visual aids and posters.  I indicated to David I already owned the Sky & Telescope Pocket Sky Atlas and a smaller version of the wheel night sky star guide (the circular atlas resting on top of the poster in the upper left hand corner of the table shown in the photo above).

Dad and I wondered among the scopes, waiting for twilight to fade and the stars to emerge.  Saturn and Mars, along with Spica and Arcturus appeared very early and most of the scopes honed in on our ringed neighbor.  By 10:30 pm, the skies had darkened enough to begin hunting for some of the brighter Messier objects.  Mike graciously asked me (several times over the course of the evening) what I wanted to observe next.  I drew a blank every time because my goal had been to see the Milky Way, not any specific object viewable in a scope.   He obligingly filled in the blank by touring through clusters, nebulae and a galaxy found in the constellation Sagittarius, Scorpius, Hercules and Ursa Major.   I tweeted the objects as we found them so I would have a record of what we saw and when.

Coathanger
Brocchi’s Cluster, also known as the Coathanger: a conspicuous asterism easily seen with binoculars in the constellation Vulpecula (via Wikipedia)

My dad and I also used his binoculars just to see what we could see with them (as opposed to a scope).  The highlight of that side project included finding Brocchi’s Cluster (more commonly known by the asterism ‘the Coathanger’).  One of the other club members used the Summer Triangle as an aid to locating the Coathanger.  As stated in the Wikipedia article: “It is best found by slowly sweeping across the Milky Way along an imaginary line from the bright star Altair toward the even brighter star Vega. About one third of the way toward Vega, the Coathanger should be spotted easily against a darker region of the Milky Way. The asterism is best seen in July-August and north of 20° north latitude it is displayed upside down (as in the picture above) when it is at its highest point.”

* Update * (added after original publication):

I completely spaced out tweeting during the eleven o’clock hour.  During this time, Mike disconnected the Goto electronics on his telescope and set me to star hopping for objects near Sagittarius.  The first one he tested me with was finding two small globular clusters a small hop away from the gamma star in Sagittarius (the star the delineates the spout of the teapot).  If I could find these two clusters, Mike told me I should be able to see both of them at the same time in the eyepiece’s field of view.  After about five minutes, I spied a couple of small fuzzy balls, not as distinct as the surrounding background stars, but I thought they might be the clusters.  Mike confirmed I had found them by doing a ‘happy dance’ and sing-songing ‘she found them, she found them’ for all to hear.  The designations for these clusters are NGC 6522 and 6528.

Mike next set me to finding either M69 or M70 (also hanging out in Sagittarius, but in the bottom of the Teapot).  I glanced at his star chart and used his excellent Telrad finderscope (which had a nice large field of view and an easy-to-use red bullseye) to quickly locate one of the Messier objects (probably M69).  Again Mike did a happy dance and song.

Mike went looking for another globular cluster, this time between Sagittarius and Scorpius, designated as NGC 6380.  I found this one especially interesting because of it’s apparent close proximity to a star.

The third test proved my undoing.  Mike moved his scope to Antares in Scorpius and set me to finding M4.  I didn’t review his star chart and spent several minutes attempting to find it.  Eventually, I gave up and Mike located it.

Teapot Asterism (for Sagittarius constellation)
Teapot Asterism (for Sagittarius constellation)

Despite all the mesmerizing Messier distractions, I did succeed in observing the vast sweep of our Milky Way Galaxy.  I learned a couple of cool memory aids and bits of trivia about finding the ‘heart’ of the galaxy and the path it takes.  Cygnus, the swan constellation, also sometimes known as the ‘Northern Cross,’ flies along the Milky Way, pointing directly to the heart of the galaxy.  To find the Milky Way’s heart, locate the Teapot (an asterism for the constellation Sagittarius), visible along the southern horizon during July and August, and imagine steam rising from the spout.

I even attempted to photograph the Milky Way using my simple tripod and DSLR camera, but without an equitorial mount of some kind with a tracking system and the digital photo editing software (to stack multiple repetitive exposures), the best I could accomplish was a three or four second exposure (using ISO 800) and fiddling with the brightness/contrast after downloading:

Steaming Teapot

I also took photos of Cygnus swimming in the Milky Way, the Summer Triangle, the Big Dipper over the dome of the observatory and several of the southern horizon.  To see the entire album, click on the photo at the top of this blog.

Soon after 12:30 a.m., Dad and I thanked Mike Sterling for the guided tour of the summer sky.  We packed up our gear and drove the hour home, where I finally drifted off to sleep after two o’clock with visions of Messier objects dancing in my head.

Dad and I had a blast and my husband is now having second thoughts about  staying home last night.  Many thanks to David Hudgins, Mike Sterling and the other members of the Astronomical Society of Kansas City for throwing a fun mid-summer star party.

Heat Bubble Bursts Just in Time for Summer Stargazing

Powell ObservatorySaturday evening I headed south to Louisburg to volunteer for my second scheduled night of the 2012 Powell Observatory public season.  My dad decided to tag along, to enjoy the show and help keep me awake for the long drive home.  We left Lansing about twenty minutes after five and my car’s external thermometer reported 106 to 107 degrees, which has been our afternoon average for about a week now, give or take two or three degrees either way.  We stopped in Bonner Springs to grab a quick, cool sandwich from Subway and returned to the highway just shortly after six o’clock.  I needed to be at Powell Observatory by seven o’clock to help prepare the facility for the weekly public program and observing night.

As we approached Louisburg from the north, I noticed a definite increase in the wind, so much so that my car was jostled several times.  At the same time, I noticed a significant drop in the external temperature.  By the time I exited US-69, the thermometer read 92 degrees, and was still falling.  Except for early mornings the past couple of weeks, I had not seen or felt such low temperatures while the sun still shone.  I pulled into the west observing field parking area and realized I was again the first person to arrive.  Since the temperature had dropped, I turned off the car and opened all the windows.  The breeze felt incredibly refreshing.

My team leader arrived within a few minutes and I received my Powell Observatory ‘Staff’ T-shirt, which I changed into as soon as the building was unlocked.  I helped setup the class room for the program, ‘Sounds of Space.’  Another ASKC member arrived and setup his ten-inch Dobsonian for solar observing and I caught a glimpse of some great sunspots before our public guests began arriving.  The clouds provided some dramatic solar observing situations.

I repeated my role as gatekeeper and accepted donations from the public and queried them for their ZIP codes to record for future grant petitions.  The first group of twenty-five guests began the ‘Sounds of Space’ program at 8:30 p.m., but I soon had at least that many waiting for the second showing. At one point as I sat waiting for more guests to arrive, what I thought was a stray dog wandered into the observing field, soon followed by three horses, two with riders and a third colt between them.  They trotted across the field to the west, with the dog trailing after, riding off into the sunset … literally.

Constellation Scorpius
Constellation Scorpius

As the sky continued to darken, despite a few wispy clouds, we opened the dome so those waiting for the next program could observe Saturn and a globular cluster found in the constellation Scorpius.  I didn’t get a chance to look at the cluster through the 30-inch scope, but I believe they looked at M4, which is near the bright star Antares.

We ended up having nearly ninety public guests Saturday evening and ran a third showing of our program.  After the last two guests had left the dome a bit after eleven o’clock, I quickly snuck a peak at the Ring Nebula in the constellation Lyra, one of the Messier Objects I’ve been trying go get a glimpse of for quite some time.  Lyra is also home to the very bright star Vega, one of the three stars that form the Summer Triangle.

As the final guests drove away, my team members and I began cleaning the building and storing chairs, tables and other items for the next Saturday.  I signed myself out of the Observatory at 11:35 and gathered up my dad for the long drive home.  He related information he’d gleaned from another team members about various types of Dobsonian telescopes and helped keep me alert as we sped north towards Leavenworth County.

Next week, we present a program on ‘Our Amazing Moon’ and the following week we’ll pose the question ‘Is There Life Out There?’  We look forward to showing you the astronomical sights (and sounds).

Until then, Keep Looking Up!

Meteor Sprinkles Likely

My husband is a night owl.  Ironic, since I’m the one with the astronomy bug, but can’t seem to keep my eyes open after nine o’clock.  Saturday evening, Terry went over to a friend’s house to watch the latest UFC pay-per-view fight.  I looked forward to an evening of quiet, watching a movie, reading a book and making sure Apollo got extra dog treats.  Before Terry left, though, I asked him to wake me up after midnight, preferably between two and four in the morning, so I could take advantage of the dark of the moon and a meteor shower. He remembered and got me out of bed at 3:30 a.m.

Vega in the Constellation Lyra
Vega in the Constellation Lyra

I shook myself awake and staggered outside in my flip-flops.  I drug the folding chair to a better location on the patio, and leaned back, stretching out my legs in front of me so my head rested comfortably on the chair back, allowing me to see nearly all the sky overhead.  My eyes immediately spotted Vega, the brights star in the constellation Lyra.  As I mentioned in Friday’s blog post Meteors After Midnight, this weekend’s meteor shower appears to originate from the constellation Lyra, hence the name “Lyrid Meteor Shower.”

Constellation Scorpius
Constellation Scorpius

Within ten minutes, I spotted a meteor.  I decided I needed a sweater or a blanket, so I went back inside to find something to keep my upper body warm and protected from the wind.  I settled back into the chair and gazed around the night sky, trying to connect the dots and recognize and memorize some constellations.  I easily spotted Scorpius (aka Scorpio) almost due south of me.  I could not see my own birth month constellation, Libra, directly west (right) of Scorpio because the stars that form the scales are too faint to be seen from my backyard.  Another interesting bit of trivia about my husband: He’s a Scorpio, whom Libras are never supposed to marry.  According to Chinese astrology, Terry and I went supposed to marry either.  In eight days, we celebrate our 26th wedding anniversary.  Go figure.  But back to Scorpius.  The bright star, Antares, flashed red or green, probably due to the atmosphere and it’s proximity to the southern horizon.

At four o’clock, I went back inside to steep a mug of tea.  I boiled some water in the microwave and selected Irish Blend loose leaf tea (my favorite).  Another five minutes later, I had a piping hot perfect blend of tea and sugar to take outside with me.  While I waited for my tea to steep, I tried to memorize the constellations displayed on the ‘Guide to the Stars’ wheel I purchased recently for Terry.  I set it to the appropriate time of night and month/day so I could identify the stars and constellations I saw above the roof of my house.  No matter how hard I tried, though, I could not find the constellations Ophiuchus or Hercules, which should have been easily spotted between Lyra and Scorpius.  I guess I just couldn’t see enough of the stars to connect the dots and learn those two new constellations.

At one point, a large bird flew directly overhead, barely skimming over the roof of my house.  Once the bird cleared my roof and flew over the court, the lights from the houses ringing our cul-de-sac lit the undersides of its wings.  I think it might have been an owl, but I can’t be entirely sure.  My eyes were focused farther away, watching for falling meteors, than a few feet above my head.

I saw two more meteors before I decided to call it quits and go back to bed.  I gave up at 4:30 a.m.  I had hoped for a few more than just three total for the night.  The ‘forecast’ for the meteor shower claimed upwards of twenty per hour, but I saw only a sprinkling.  Adding the ones I saw last night to the two I saw Friday night at the star party, I observed a total of five meteors this weekend.  Clouds have moved in from the north today (Sunday), so I doubt I’ll get a chance to try again tonight.  Besides, it’s a work night which means I need to be asleep by nine o’clock.

What a Difference a Week Makes …

This will be a conglomeration of star gazing journal and family events and I only have fifteen minutes to spit it out! So here goes:

First, the star gazing report:  My dad and I traveled to Winfield to visit my aunt and uncle for the weekend.  Since the weather was forecast to remain calm, clear and the moon was just barely a sliver, I took the telescope and accessories with us.  We spent the day visiting, enjoying experimental cooking from my aunt and uncle (which was delicious, don’t get me wrong) and doing fall tree trimming and another household repair a la my dad.  I have photos of a couple of the close calls my dad avoided, but that will have to wait for another post.

Later in the evening, after another wonderful new recipe for dinner, as the sun set and the moon quickly followed, we setup the telescope just in time to catch a glimpse of the craters of the moon along the terminus.  Everyone got a chance to view before the moon slipped towards the horizon and behind the tree line.

Now, we waited for Jupiter (which was visible already) and the first few stars (Altair, Deneb and Vega).  We relocated the telescope to the backyard (for a better angle on Jupiter) and my aunt invited a couple of neighbors to view Jupiter’s spectacular display.  We discovered, over the course of the evening, the Jupiter’s moon move quite fast, so much that when the evening began, we only saw three moons, and as it progressed we saw the fourth appear and a couple others move out and up in their orbits.

My personal goal for the evening was  a second attempt to find Comet Hartley 2.  So I was just killing time until the skies darkened enough to make the attempt.  In the meantime, I showed my aunt and uncle the double star in the Big Dipper (Mizar/Alcor)  and of course we began to see the great sweep of stars for the Milky Way.

We took a break (about an hour or so) to sit inside and rest our backs (tree trimming was only a regular activity for my father) and returned to hunt for the comet.  My dad and I tried for another hour, but haze, trees and light pollution were not helping us.  We finally gave up around 11:00 p.m. and headed off to bed.

I woke at my normal 5:00 a.m. timeframe and migrated up to the dark living room.  My uncle soon arrived and we both exited outside to determine the location of Cassiopeia.  That region of space was still not dark ‘enough’ I believe and clouds were rolling in fast from the west.  I did point out Orion and Sirius almost directly due south at that time of morning.

After another wonderful meal (this time breakfast of course), we visited and discussed books, movies, politics, religion … all the usual topics I’ve come to know and love with my close family.  Lunch was a local Chinese buffet followed by a mini-tour of Southwestern’s campus, where it’s celebrating it’s 125th year and Ron’s art (as an alum from 1968) is featured in Baden Hall.   Recently remodelled, it had formerly housed some of Arthur Covey’s artwork and still sports a block dedicating the fireplace from Arthur to his art professor Dunlevy.

Rain rolled into Winfield and followed Dad and I north along the turnpike, peaking in Emporia where we stopped for supper and Braum’s ice cream, but tapered off as we continued northeast along I-35 to K-7 in Olathe and finally reaching Lansing/Leavenworth by 8:00 p.m. — only one hour late mostly due to too much talking (missing exits) and stopping for gas and food.

A wonderful weekend getaway in Winfield I hope to repeat in the future.

Ciao,
