Comet PANSTARRS faded in April and was too faint to be observed from the urban conditions at Griffith Observatory. However, from wilderness locations with clear horizons and dark skies the comet was still visible through binoculars and telescopes. The comet was best positioned for viewing in the north east sky just before dawn.
Comet PANSTARRS was visible to observers in southern California through much of March 2013 above the western horizon for more than an hour after sunset. It was clearly visible through binoculars, but only faintly visible to the unaided eye.
Visitors were able to observe Comet PANSTARRS through Griffith Observatory's telescopes during the month of March, as long as skies were clear, the Observatory was open, and the comet was visible.
