Comet ISON is currently gliding across the constellation Virgo, which makes it a morning sky object. To see Virgo, you need to gaze eastward starting around 4 A.M. local time. This week the comet will rise about three hours before the Sun, making it visible to the eye, to binoculars, or in telescopes for an hour or so while the sky is still relatively dark. The Moon is another factor that observers need to contend with. The reflected light from the Moon makes spotting fainter objects more challenging, in effect dimming down their light. The Moon begins the week a day past First Quarter, in the evening sky, but ends the week at Full Moon, when it will interfere with observing all night long. So observing the comet in the early and middle part of this week will be easier than at week's end.
Meanwhile, another comet also inhabits the morning sky, Comet Lovejoy (C/2013 R1), which is putting on an impressive show in the northern part of the constellation Leo. Lovejoy is visible during the same predawn hours as ISON, and last week Lovejoy was actually a bit brighter than ISON. You can find Lovejoy moving to the northeast along the top of Leo's so-called Sickle, the backwards question mark asterism of this bright star group.
