COMET C/2007 B3 (GARRADD)

G. J. Garradd reports his discovery of a comet with a faint coma extending 10" to the northwest on Siding Spring Survey images obtained with the 0.5-m Uppsala Schmidt telescope (discovery observation tabulated below). Following posting on the Minor Planet Center's 'NEOCP' webpage, R. Ligustri (Talmassons, Italy) writes that his CCD images from Jan. 27.45 and 27.51 UT (taken remotely with a 0.25-m reflector at Mayhill, NM, U.S.A.) show a 22" coma of total mag 17.6-17.7. C. Hergenrother adds that a co-added 600-s R-band image taken on Jan. 29.51 with the Catalina 1.54-m telescope shows this object to be a comet with a coma 8" in diameter and a tail 40" long in p.a. 305 deg.
