Where is it in the sky?
This article is dated yesterday, so hopefully it's reasonably accurate:

"It [Comet Holmes] can be seen in the constellation Perseus, and through binoculars appears as a large fuzzy ball of light with a bright center. A small tail is developing but not yet visible without a telescope.
After sunset on a clear night, sky watchers should face north, find the "W" shape of the constellation Cassiopeia, then look down and to the right to spot the comet."
For those not familiar with the night sky, here's an interactive sky chart, that allows you to generate a map of the sky on any date, at any time, for any location on earth:
