Comet PanStarrs in the norther sky
Comet PanStarrs, which has swiftly moved from the southern
hemisphere to the northern hemisphere, is now shining in the northern sky
and just about to become a circum-polar comet visible all night.
This photograph was taken around half past three in the morning
on April 11, when the comet was still relatively bright showing its majestic
tail. It is at magnitude 5.5 and faintly visible to the naked-eye. Great
comets often shine hugging the horizon, which makes it difficult to see
with the naked-eye. The reddish color of the comet in the photograph is
perhaps caused by the atmosphere low on the horizon.
C/2011 L4 (PANSTARRS)
5-minute exposure at 3:33 am on April 11, 2013 (J.S.T.)
