Comet Lulin animation Feb 23 UT

Contents

Animated GIF image of Comet Lulin C/2007 N3 from Feb. 23 UT. Images show plume from the ion tail preceeding comet and anti-tail from the dust trailing behind the comet. Field-Of-View is about 20x30 arc minutes, just slightly smaller than the Full Moon. Individual frames are stacks of 10 exposures of 30 seconds each, thus the elongated star trails show how much the comet has moved in 5 minutes time.
