Comet 2013 US10 Catalina has been in the morning sky for northern observers since the start of December. Not that there's been much chance to see it! The weather here has been mostly appalling for much of that time.
For a few days around the New Year period Catalina will buzz past Arcturus - the brightest star in the northern sky. Arcturus is an orange giant star - there really is no mistaking it in high in the south east before dawn breaks. Arcturus provides an easy signpost to Comet Catalina as the year ends.
A clear transparent sky away from light pollution is essential to view the comet. It isn't quite bright enough to be visible without optical aid: binoculars or telescopes will easily show it.
Here is a closer view of the sky around Arcturus. The star and comet will appear closest together in the sky on New Year's morning.
A more detailed finder chart for the comet can be found here.
