There's always things worth looking for in the sky, but especially now. Comet Holmes is out and about and viewable. Get your butt off the sofa and get out on any dark night soon and watch . I promise you won't be sorry you did . Starting November 26th, there's a good dark-sky period between when twilight ends and the Moon rises (depending on the latitude where you live). This dark-sky window is only about a half hour long on the 26th (near latitude 40° north) but grows about an hour longer each night thereafter. Comet Holmes came into view October 24th. At first the expanding dust cloud around its icy nucleus appeared so small that it looked like a bright star. Within days the cloud spread out wider, the “star” became a fuzzy round disk. Since then the disk has been getting wider, and as the dust has spread its brightness has greatly dimmed. As of late November the comet is about 0.7° wide, larger than the apparent diameter of the Moon.
Will Comet Holmes erupt again, as it did when discovered in 1892? Get out and take a look. This visitor will be among the stars of Perseus for months.
