COMET P/2009 Q1 (HILL)

On Aug. 27 R. E. Hill with the Catalina Sky Survey 0.68-m Schmidt found this diffuse comet with no clear condensation and a 12"-15" coma with a broad, diffuse tail about 20" long in p.a. 250 deg. The object was then included in the neo confirmation page (NEOCP) for other observatories to confirm and follow up.

On Aug. 29.0, I stacked twenty 2-min images to find the object very diffuse with a round coma of size 12" and a tail 20" long in p.a. 249 deg.

This (above) is a cropped non-zoomed stack composition of 29 images of 2 minutes each taken with the .40m Ritchey-Chretien F10 + CCD at La Cañada, the North is up and the East left.
