Comet Lulin (C2007 / N3) on February 24, 2009 at approximately 02:24 Universal Time. North is to the right in this image. Comet Lulin's Anti-Tail points to the east and it's blue ion tail points to the west. The anti-tail is the dust tail that appears to point in the opposite direction from the regular ion tail and is caused by an effect of the orbital geometry and our viewing angle here on Earth when the comet passes through the ecliptic.
