swordgeek writes "Comet 17P/Holmes, a relatively obscure and dim object has suddenly flared to be literally a million times brighter than it was two days ago, going from below magnitude 14 to 2.8 in less than 24 hours. It is just outside of the constellation Perseus, which puts it high in the sky and ideal for viewing at this time of year. The comet is now readily visible with the naked eye, and remarkable in binoculars or a telescope. This is a completely unexpected once-in-a-lifetime event, so get out your finest optics (even if it's just your eyes) and go comet watching! No one knows how long this will last, so grab the chance while it's there."
