Here are some helpful pictures of where Comet PanSTARRS might be found from sundown on Friday, March 8 through the night of Saturday, April 20th.
The pictures are from a standard piece of astronomy software, and the image itself simply represents a generic comet. There is no way to know what PanSTARRS will actually look like until it comes into view.
Hopefully, though, this will only be our first encounter with a Great Comet in 2013. If it survives its close encounter with the Sun, Comet ISON may well put on an even better show late next Fall and early next Winter (again, the images of the comet are merely guesses as to what ISON might look like).
