Comet Ison: Perihelion is now
Nice video here, along with a sky map telling you where to look in the early morning. Instructions for viewing it in daylight here – wear sunglasses and take their advice to use a stationary object, not your thumb, to block the sun. And latest images here. I am going out now with my trusty camera and looking for a lamp post, but it may be too close to the sun already.
Update: Here is a remarkable picture from the Nasa site above, taken on November 25.
