This picture shows you a figure of comet 2001Q4 NEAT in Oct 2004, three month later since I have captured in July. In this day the comet has positioned at 69 degrees in declination, a circumpole, can be observed all night. The comet has a dimmed coma of 11th magnitude, but has an extraordinary thin and long tail streched toward southwest about 30 arc minutes in length.
