Comet Tail Still Visible Up North
It's been several days since anyone in the Northern Hemisphere saw the head of Comet McNaught. But the comet's tail is so bright and long that numerous northern observers have spotted it two or more hours after the head has set. All you need to try is a site with a good western horizon that's far from any artificial light pollution.
Comet McNaught, Spectacle of the Far-Southern Sky
As of January 18th, Comet McNaught is barely visible from the Northern Hemisphere, but the show is just beginning for observers at mid-southern latitudes.
Comet McNaught Heading South
If you live in the Northern Hemisphere, Friday was your last good opportunity to catch Comet McNaught in the evening twilight — though January 13th isn't completely out of the question. On January 14th or 15th, the comet will become a showpiece for observers in the Southern Hemisphere.
Comet McNaught Brightening
Comet McNaught has brightened rapidly in the last few days. It's now bright, beautiful, and, if you're fairly far north, easy to see at dawn and dusk — if you know where to look and have an unobstructed horizon and perfect conditions. It's now a naked-eye spectacle from far northern latitudes, where the observing geometry is most favorable. The farther south you live, the lower the comet is in the twilight.
