Observation Log 10/30/06: Comet SWAN (C2006 M4) #3! Plus my first M13, not at all my first M31


Comet SWAN in Hercules
I'd read that Comet SWAN would be impossible to see after last weekend, since the Moon is 62% illuminated, shining at -12.7 magnitude, and it culminates at 6:53PM EST, which is prime viewing time for the setting SWAN before it drops toward the murky horizon. Perhaps it was the 75mph wind storms we've had for the last 24 hours, but the sky was quite clear of haze tonight, and SWAN was an easy target.

I was also fortunate to stumble upon M13, a globular cluster orbiting outside the plane of the Milky Way, which I'd never actually looked for before, but I knew it would be nearby SWAN. Just for fun, since I was already out with my Canon 10x30 IS binoculars, I also had a peek around Cassiopeia, and of course M31, the Andromeda Galaxy. [end]

Observation Log 10/26/06: Comet SWAN (C2006 M4) again!


Comet SWAN has brightened dramatically in the last two days, according to reports at Space.com and SkyTonight.com. Dennis Persyk has an impressive page of pictures and a movie of Comet SWAN. Last night I went out, on a whim and without adjusting my eyes to darkness, with only my Canon 10x30 IS binoculars. The sky was challenging--it would have been a fantastic night if it were not for the low, fast-moving clouds, which averaged 70% coverage. Sweeping the comet was almost entirely luck, but I found it within five minutes, and got only two minutes to observe. At first it seemed quite similar to my last observation, but with averted vision it was quite striking. There was a clear, bright nucleus within the coma, and I could barely make out a hint of a vertical tail. I thought I saw two tails for a few moments before the clouds started to obscure the comet. SWAN was even visible though some light cloud cover for 15 seconds or so, then it was blanketed completely by a thick cloud.

I stayed outside for 15 more minutes, and spent a further 15 a bit later, having re-checked my star charts. Though I got several very good looks at the correct part of the sky, I wasn't able to re-aquire the comet. If I were more confident in my skills I might say it had darkened considerably in that interval, but... I'm not that confident! I did spot a very unusual satellite, which may have been the "COSMOS 482 DESCENT CRAFT" This satellite seemed to blink ~ 7 times in a second, disappear for a few seconds, and repeat. I found its name in Starry Night, but I couldn't find any other information on the internet. Perhaps it is spinning and tumbling at the same time.

I recommend you get a look at Comet SWAN if you can. Most comets are coming back this way eventually; not SWAN. It's on an unusual hyperbolic orbit which makes its return extremely unlikely. SWAN will most probably roam interstellar space for eons. [end]

Observation Log 10/18/06: Comet SWAN (C2006 M4)


The comet was setting in the skyglow and sunset to the WNW, but I definitely picked out the faint fuzzy of the coma. I wasn't even expecting to see it really, so it was a doubly nice surprise. I rechecked a few times, star-hopping from Alkaid, past Boötes' "pipe" (using Rey's outlines) and between Seginus and Nekkar, with HIP72582 and HIP72469 pointing right at it. No doubt, there it was, with only Image-Stabilized 10x30 binoculars.

I didn't even mention this. A few nights ago, that I couldn't sleep and my wife was away on business, so at 3AM I went outside in my pajamas and spotted Kemble's Cascade, the Andromeda Galaxy, the Orion Nebula, and spent a little time aimlessly wandering through the skies with my Canon IS 10x30s. I came back in after 30 minutes and went right out! What a great way to relax before sleep! The only downside was my neighbor's Halloween decorations, which must be programmed to make spooky, "Mwah hah heh heh heh Aaaarrrrggghhhhhh OooooooOOOOOOoooooooo" noises every so often. That kind of freaked me out the first time I heard it. It made me glad I had about five pounds of metal and glass on the end of a 30" neck strap, just in case I need to swing it around, you know?

Observation Log 8/12/06: The Perseid Meteor Shower


Between the 11th, 12th, and tonight (the 13th) I'll probably have 6 hours of observing time. Each time out, thanks to the nearly-full moon, I see only the brightest meteors. Even so, I've seen on average 3 per hour, and I've enjoyed each one. My favorites are the meteors with the sparkly golden tails that linger a few seconds. About 1/3 of my sightings have been like that, with the rest divided between bright blue/white, quick-moving meteors, and the rest a mix of yellowish meteors with no tail to speak of. Even with the relative paucity of events, it's been fun.

The 2006 Perseid Meteor shower is here!


I just spent a pleasant hour outside watching a few beautiful meteors. Two long, slow ones with golden sparkly trails, and one faster blue/white one without a trail Read Sky and Telescope's Guide to The Perseids! Here's Astronomy Magazine's coverage, this from New Scientist, from Space.About.com... and, of course, NASA.

Observation Log 4/30/06: Comet Schwassman-Wachman (73P)


Image: Comet Schwassman-Wachman (73P)
My first look was a bit of a disappointment, since my binoculars just didn't collect enough light. So, tonight I got out my Celestron 8i and my 2" Naglers for a better look

Observation Log 3/28/06: Got the scope out to try the Dew Shield. Saw some planets & moons, found a surprise!


Tonight was the clearest, best seeing night in a while. So I got out the Celestron 8i telescope to try out my new Dew Shield. Not having any specific goals for the night, I played a bit, and found the beautiful NGC 1502 cluster

Observation Log 3/27/06: Revisiting a few clusters, and... what the heck is Mars doing way over there?


It was a rare clear night, the moon isn't out, so I grabbed the Canon binoculars and got outside for a half hour. I saw the Beehive Cluster, the Perseus Double Cluster, Kemble's Cascade, Saturn, and... Mars... but why is it so far north?

Observation Log 3/5/06, 4AM: Found Comet Pojmanski


Image: Comet Pojmanski
I didn't plan it this way, but I awoke at 4AM this morning, looked outside and saw a gorgeous, clear sky, and was outside 5 minutes later. Finding Comet Pojmanski (here's another picture) was easy with a quick reference Sky & Telescope's article and to Starry Night. I started with the Canon binoculars, could only see a faint fuzzy, so I went back inside for the Oberwerks binoculars & tripod. The view was pretty much the same, with many more stars visible in the background, but with a slight green tint to the coma. I couldn't discern a tail, even with fully dark-adapted eyes and about 15 minutes dedicated observing to the one object. The Sun did have a noticeable progressive effect on the contrast of the eastern sky as time went on.

Observation Log 2/28/06: I can't believe it, I just watched a SuitSat flyover!


Image: Path of SuitSat
I wrote earlier today about my meticulously geeky plans to try and bag SuitSat. I just got back indoors from the attempt, and I don't believe it, but I did it!

The short story is that the talking laptop was the real key. That, and having practiced the flyover several times using the talking AppleScript and Starry Night with all the labels and lines turned off. Oh, and a bit of damn good luck at just the right time. I used my laptop, my Oberwerks 11x70 binoculars on a cheap tripod, and my Canon 10x30 IS binoculars for quick spotting.

Once I got outside, I couldn't see my first and last guide stars, and Cepheus was lost in the city-glow to the north. I had only left 15 minutes to set up, get my eyes dark adapted, and practice acquiring the target stars. It wasn't enough. I picked a spot with the widest view I could find, which barely included Alpheratz and Pherkad. Algenib at the extreme left, and AIkaid, to my extreme right, were both behind the trees. I got the laptop set up and got down to finding the target stars I could see. I had intended to use the Great Square to find Alpheratz, but the other three stars were behind the trees. Then the laptop told me SuitSat was coming above the horizon, and I had 85 seconds before it passed Algenib. I used the time to try and find Iota Cephei and Alfirk. I was close, but not positive. The laptop said 10 seconds to Algenib. I swung the Oberwerks over to my best candidate for Algenib and waited to hear the marks for entering and exiting the FOV. Nothing. Then the laptop said I had 25 seconds to frame Alpheratz. I realized then that's what I had been looking at all along. I stayed on that star, cheated the FOV down and to the right for a better view, and waited. A moment after the laptop said I should see SuitSat, there it was. It was much dimmer than I expected, perhaps a bit brighter than 6th magnitude at this point, but I immediately noticed that it came in and out of view every five seconds, which matches the suit's spin rate quoted on A. J. Farmer's blog, which also reported the photographic SuitSat observation from Singapore. SuitSat was also traveling faster than I'd thought, and I kept lifting the legs on the cheap tripod as I tried to keep up. I held SuitSat in my Field Of View for about 15 seconds, and lost it somewhere near Iota Andromedae. The laptop said I had 27 seconds to frame Iota Cephei at the top of my FOV. I had to guess again. Thankfully, I had to foresight to add a few informational spoken messages, and at 6:44:00, the laptop said, "SuitSat is directly below Cassiopeia at 30 degrees altitude." That was an easy one, and within 15 seconds I'd reacquired SuitSat, and I held it until it ducked behind the trees, just past Pherkad.

Observation Log 2/27/06: 19°F, spotted Mercury, but didn't catch SuitSat (visually)


Mercury is just past its greatest eastern elongation (eastern means visible at night, western elongation is visible before sunrise), so I spent the afternoon driving around, looking for an observation spot with a clear view to 255° (where the sun sets today). I found a beauty, right next to a police station. I came back at the appointed time, bagged Mercury, but missed SuitSat, which was supposed to pass almost directly overhead.
