Starting tonight, comet PANSTARRS, which was first discovered in images taken by the Panoramic Survey Telescope and Rapid Response System in 2001, should finally begin to become visible in the Northern Hemisphere, weather permitting. The comet will appear very low near the west-southwest horizon about a half hour after sunset.
By this coming Tuesday, March 12, the comet will sit almost directly above the western horizon, less than 5 degrees to the left of a very narrow crescent moon. The comet will slowly move higher in the sky, shifting slowly toward the west-northwest part of the sky during the middle and later part of this month, and become gradually dimmer as it pulls away from both the Sun and the Earth.
The tail of the comet, if visible, should appear to be pointed upward and tipped slightly toward the left through mid-March, before tipping more toward the right or the remainder of the month.
