Title: Comet Pan-STARRS
Location: Low on the western horizon after sunset
Date / Time: March 10th - 24th, 2013
Comments: I highly recommend this informative YouTube video from NASA ScienceCasts: "A Naked-Eye Comet in March 2013." http://www.youtube.com/watch?v=OZlenAvqLCI . Visit SPACEWEATHER.COM for the latest updates & images of Comet Pan-STARRS (C/2011 L4), which will likely become naked-eye viewable in mid-March, just after sunset, low on the western horizon. On March 5th, comet Pan-STARRS made its closest pass by Earth, at a MERE 100 million miles from our planet. On March 10th, the comet made its closest approach to the Sun (0.3 AU) and has brightened substantially as its nucleus vaporized. On March 12th and 13th, the comet will appear in the west, just after sunset, not far from the crescent Moon. On the 12th, Pan-STARRS will be just to left of a slim crescent Moon. On the 13th, it will be approx. 10-degrees below the Moon's crescent. On the 14th, look for the comet 20 degrees below the Moon, and perhaps a little to the right. From March 14-18 the comet will be in the WNW at dusk (gradually moving to the right from one evening to the next) & will continue to set at 7:45. However, its brightness will begin to fade & light from the waxing Moon will become more of an interference. From March 19th thru the end of the month, Pan-STARRS will still hover in the west at dusk, but will be harder to see as it fades in brightness.
