As you prepare to brave the cold, clear nights of fall and winter observing, why not consider measuring yourself against an artful and subtle observing quarry, Sirius B?
The RASC Sirius B Project Team is pleased to announce the launch of the Sirius B Observing Challenge website, which contains everything you need to pit yourself against this tough celestial entity. Venture where all too few observers have gone before!


Will the world end in 2012? Of course not!
