Comet Lovejoy (C/2014 Q2) is now at peak visibility for the northern hemisphere. This excellent article from Sky & Telescope gives some history, images, and detailed charts. It is a good read. To save you time, I will summarize.
If you have a clear sky, binoculars, or a small telescope, you should be able to see it. It might be visible to some viewers with the naked eye under the best of seeing conditions. Here is a 90 second image from the University of Iowa Robotic Observatory in Arizona taken January 7. To your eyes, it will appear as a fuzzy patch instead of a distinct star point. It might even be a little blue-green.
It will be positioned best for viewing during the evening hours after 6 pm for the next week or two before it starts to dim. The exact time is not critical.
Where To Look?
Look to the right of the constellation Orion in the southeast. Lovejoy will be straight to the south at 8 pm local time. This chart from Sky & Telescope will make it easy to locate. There are some easily recognized sky features along the path such as bright Aldebaran and the Pleiades. Click on the chart. Then make a print out so you can reference it while searching on any of the coming days. Good luck. Clear skies.
