Comet ISON has come and gone, but lovely Comet Lovejoy (C/2013 R1) is still going strong. It is now at or near peak brightness, and well placed in the Northern Hemisphere's predawn sky.
Nobody would claim that Lovejoy is the Comet of the Century, but at magnitude 5.0 or thereabouts, it's one of the brightest comets of the year. Lovejoy is visible to the unaided eye under dark skies and an easy catch in binoculars even under bright urban skies. It has a large, bright head and sports a tail about 2° long.
Look about 30° above the east-northeast horizon 90 minutes before sunrise, just before the sky starts to brighten. Lovejoy is left of (and a little below) bright Arcturus and almost directly below Alkaid, the end of the Big Dipper's handle. Click here for a detailed chart.
Lovejoy will appear about 1° lower each successive morning, and it will become difficult to see once the nearly full Moon enters the predawn sky on December 15th or 16th. So get out and see it now!
