Some Winter favorites are up there: Pleiades (‘Seven Sisters’ and where ‘Subaru’ gets its name) and Betelgeuse (in Orion). Aldebaran, Betelgeuse & Menkar are ALL orange giants and you can see the orange.

Enjoy. Look up in wonder.


We Saw C/2011 L4 (Pan-STARRS) Tonight From Alton, New Hampshire, Through Binoculars, Thanks To Heads Up From Dave Eagle.

C/2011 L4 (Pan-STARRS) fron New Hampshire

C/2011 L4 (Pan-STARRS) seen with binoculars from Alton, NH, on April 6, 2013. Click to ENLARGE.


Dave Eagle, in an e-mail this morning, gave me a heads up that C/2011 L4 (Pan-STARRS) is still visible (though I am not sure whether it is still naked eye). Per Dave, and he would know, it will be close to ‘M31‘ — i.e., Andromeda.

It was more of less where I told you to look this morning. I used those same instructions, which were: For us in New England, that would be low in the Northwest sky around 8 pm. I think trees will be the problem for us. From what I can see from my trusty Sky Charts our best bet would be to start with The Pleiades (the easy to spot ‘Seven Sisters’/Subaru cluster). They (i.e., The Pleiades) should be close to West around 8 pm. Then start scanning North from there. With luck you should be able to spot the ‘W’, the upside down crown, of Cassiopeia. M31, and hence the comet, should be below Cassiopeia.

Beautiful night for admiring the firmament. Not a cloud in the sky. The cold air making everything bright and crisp. We started off on a cleared, abandoned housing estate site close by but it didn’t have enough elevation. So headed up Prospect Mountain Road to the very top. Got to see two delightful porcupines frolicking on the road. Yes, we stopped and watched. Then we turned into Ridge Road at the end of Prospect and parked right at the zenith, off the road. Now we were above the tree line. We used Google Sky Map on a Google Nexus 7 Android 7″ pad to fine tune our direction. Great App. Very easy to use. bang, Right there. Deanna could hold it up and match Cassiopeia with what is in the sky. That helps.

I started scanning with a pair of old, very old, Carl Zeiss, 10x50W binoculars. Took me a while. But then I saw it and I said: ‘WOW’! No escaping it. When you see it you know that that is different. It was rewarding. I saw Hale-Bopp, C/1995 O1, most nights for nearly a month in 1997. That made an indelible impression. I also saw Kohoutek, C/1973 E1, faintly, in 1974, after spending days clambering up hillocks in The Mumbles, near Swansea, Wales, with like minded fellow students from the University, spread over 4 months. That was dedication. C/2011 L4 was better.

Deanna thinks it is the first comet she has seen. She is not sure whether she saw Hale-Bopp. She was thrilled. She too went: ‘Wow’. It was, of course, a first for Devanee. Teischan wasn’t interested.

So this was a nice, welcome warm-up for C/2012 S1 (ISON) later this year. That should, with luck, be more spectacular.

C/2012 S1 (ISON), the ‘2013 holiday’ comet that will be at its peak in November – December 2013, could end up being the great comet of 2013‘, ‘the comet of the century‘ or even the ‘once in a civilization comet‘.

But, comets love to tease and beguile. So this is still a tad to early to get any hopes up. The comet having passed Jupiter’s orbital path around March 17, 2013 is 4.22 AU [392.3 million miles] away. If it successfully weathers its perihelion around the Sun on Thursday, November 28, 2013 [yes, Thanksgiving] , it will be an order of magnitude closer as it rushes by Earth at a 39.9 million mile separation on Boxing Day, 2013. There is a 20% chance that it might get fragmented or zapped as it is classed a ‘sungrazer‘ since it will skim by just 723,683 miles from the Sun’s surface.

Last night we had a perfect viewing night, if not for the bitter cold wind. Tonight might be better. So, lets try and get out there and have a look. Binoculars might help.
