Comet PanSTARRS

About this Object

Comet C/2011 L4 (PANSTARRS) is a non-periodic comet discovered in June 2011 that became visible to the naked eye when it was near perihelion in March 2013. The comet was discovered using the Pan-STARRS telescope located near the summit of Haleakala on the island of Maui in Hawaii. Comet C/2011 L4 probably took millions of years to come from the Oort cloud. Dust and gas production suggests the comet nucleus is roughly 1 kilometer (0.62 mi) in diameter. It was best seen with binoculars or a small telescope 40 minutes after sunset in mid-March 2013 due twilight brightness and its low elevation.

About this Image

As is usually the case with any opportunity to observe an important event, clouds kept me in during most of PanSTARRS' best unaided viewing period. I did get out one evening to capture this image.
