Two bright comets still easily visible in the northen sky

The two comets are Comet Holmes and Comet Tuttle - both visible to the unaided eye at the moment, if you manage to get away from all those inefficient city lights. If not, binoculars will help you spot the pair.

Comet Holmes, still visible to the unaided eye from a dark site, is still getting bigger - it is now three times the size of the full moon! The image to the left was taken by Toni Scarmato in Italy, with the comet approaching the bright star Algol. It will get closest to Algol on 22 January, so that will be a great time to take a look.
Because it is so big, you do not need any specialist equipment - just a digital camera with lens will do. For lots of examples, see the gallery. It is visible high in the sky, in the constellation of Perseus - halfway between Cassiopeia and the face of Taurus the bull.
But the big question that everyone is asking is - will Comet Holmes outburst again? When it was first discovered in 1892, it faded for about 70 days until it suddenly brightened again. Will history repeat itself? If so, the comet may brighten again any time now. (The full history of the discovery behaviour of Comet Holmes can be found at Gary Kronk's Cometography website.)
While Comet Holmes is very high in the sky from Greenwich, Comet Tuttle is much lower, just 25° above the horizon in the constellation of Cetus the Whale (or sea monster), well below Perseus. Images and maps of Comet Tuttle can be seen on the website.
