Limber Observatory Image of Comet Hale-Bopp


Observer: David McDavid
Location: Limber Observatory, Pipe Creek, Texas
Date: March 4, 1997 11:34 UT

The inner coma of Comet C/1995 O1 (Hale-Bopp) at 11:34 UT, March 4, 1997. North is up, east is left, and the field of view is about 7 arcmin square. This pseudocolor image is a 60 s exposure through a Bessell B (blue) filter with a Photometrics CCD camera (Thomson 512 chip) on the 0.4 m f/12 telescope at Limber Observatory. At the distance of the comet, this frame spans 430 000 km, or about three times the diameter of Jupiter. One pixel on the CCD is about 840 km, or 42 times the estimated 20 km size of the comet's nucleus. David McDavid
