Comet Lovejoy is now putting on a superb performance in the early morning sky for Northern Hemisphere observers. At the end of November, it reached 4th magnitude and was visible to the naked eye. The comet was easily seen through binoculars and small telescopes, appearing obviously non-stellar with a nice fuzzy halo and tail. For the remainder of the year, Lovejoy keeps in almost as good shape. Although predicted to fade slightly during December, it should remain an easy binocular and small telescope target, although more difficult with the naked eye.

Location and star chart

Lovejoy started December in Boötes at magnitude +4.3. Traveling in a southeastern direction it then passed just south of Nekkar (β Boo - mag. +3.5) on December 2nd before crossing the border into Corona Borealis on December 4th. The comet then moves through Corona Borealis until December 12th when it enters Hercules, remaining there until the end of the year. During this time Lovejoy is expected to decrease in brightness to magnitude. +6.0. It remains well placed for observation from northern temperate locations, appearing reasonably high above the eastern horizon during the early hours of the morning. However, from the tropics and Southern Hemisphere, unfortunately the comet won't be visible until next year.
