Comet Pan-STARRS has now become visible from Northern Hemisphere

Comet C/2011 L4 (PANSTARRS) is a non-periodic comet discovered in June 2011.

Comet C/2011 L4 probably took millions of years to come from the Oort cloud. After leaving the planetary region of the Solar System, the post-perihelion orbital period (epoch 2050) is estimated to be roughly 106000 years.

On the evening of March 11, 2013, Comet PanSTARRS was captured in a time lapse sequence as it set over the Dos Cabezas Mountains. The photos where taken from San Simon, AZ. All exposures were 2 seconds at F5.6 (ISO 800). The sequence was edited in Photoshop and assembled into a movie using QuickTime Pro.
