Hi, just saw news of a mag 11 nova in m82. Could get as bright as mag 8 over the next few days. I know its darn cold outside, but if anyone can image it, I would be happy to show it to the club next month.

Most nasa sites are overloaded, but this page works.
Select LASCO C3 and a number of frames (5 per hour) to see a cool video of the comet approaching the sun.
According to reports from the AAVSO, the nova in Delphinus peaked earlier today at a magnitude of about 4.5. I just looked at it this evening, and the nova has dimmed to 4.9. Finder & comparison charts can be found by clicking on the title above and following the links.
Janice and I went out this evening to try to see the nova that appeared today. We spent a few minutes identifying the field and then found the nova easily by about 9:55. This is the first time we've actually seen one. Thanks to Joe for the notification. This one is an easy binocular target with 7x50 binos. A chart can be found at the sky and telescope web site. John Gauvreau has determined a magnitude of 5.7 which based on what we saw is pretty darn close.
I am sure every sky-watcher can recognize CORONA BOREALIS, the beautiful constellation of the Northern Crown found in the spring sky, rising high in the East after dark.
After many years at minimum brightness (and I mean as faint as magnitude 15), the variable star R Coronae Borealis is slowly brightening again. If you have binoculars, you can watch it brighten slowly this spring until it reaches magnitude 6 again.
R CrB variables are normally bright, but can accumulate a cloud-like covering of carbon. Until that carbon shell is burned off, these stars can be dimmed up to 10 magnitudes. This star has a habit of dimming and then regaining its brightness within a few months.
Strangely, since 2007 R CrB has been only 1/10,000 its normal brightness. Moreover, whereas R CrB usually springs back to magnitude 6 quickly, this latest recovery is taking a long time. The AAVSO chart below graphs R CrB's visual brightness for the last 10 years. You can see the star's swift dip and recovery in 2003, contrasted with the several years at minimum and the most recent - very slow - recovery.
This is a star worth watching again!
