If the sky is clear, and you live in the mid-northern latitudes, you should be able to see the PanSTARRS Comet tomorrow night (March 12) and through March 18 just after the sun sets.
Sky and Telescope Magazine has a great piece online about how to spot the PanSTARRS comet . The main thing is to "...look out west around twilight...around 30 to 45 minutes after sunset."
The crescent moon should help you see it.
Madame L hopes you'll follow this link to the NASA Astronomy Photo of the Day from a few days ago to check out the beautiful photo of the PanSTARRS and Lemmon comets together over the Atacama Desert. (Madame L would post the photo here herself except that it's copyrighted.)
Also, Madame L hopes you'll check out NASA's Astronomy Photo of the Day (APOD) EVERY DAY. Today's APOD shows a volcano erupting, with lightning bolts shooting down through the eruption.
