How to view L4 PANSTARRS

Find a great site to see horizon (ie high up and view of ocean for CA coasters). Use Binoculars!


Seek out the best view of Western horizon you can find and start looking with binoculars in the evenings ~30 minutes after sunset as early as March 7th. The comet could be visible without using binoculars around March 12th but binoculars will let you see detail like the tail much better.

"The above image was taken by Ignacio Diaz Bobillo on Feb 15th through a telescope, I'm sure you will agree this is a wonderful capture and full of potential for nice show on the weeks ahead. The green colour around the coma (comet's head) is the gas/ion envelope around the comet's nucleus and the white/gold colour is the dust tail reflecting light from the sun. L4 Panstarrs sports a very high abundance of dust which indicates a fairly large and very active nucleus which should continue to brighten every day as solar heating and pressure increases."

Comet PanSTARRS is named after the person or group that discovered it. In this case, the University of Hawaii's Panoramic Survey Telescope & Rapid Response System Pan-STARRS which is an innovative wide-field imaging facility developed for astronomy. It's full name C/2011 L4 PanSTARRS is a non-periodic comet discovered in June 2011 that is expected to be visible to the naked eye when it is near perihelion in March 2013.
