Amateurs Gary Hug and Graham E. Bell, Eskridge, KS, reported their discovery of a  19th magnitude comet on 10 December 2006, showing a faint tail in p.a. 285 deg on CCD images taken with a 0.3-m Schmidt-Cassegrain reflector during the course of their minor planet search and follow up program. Following posting on the NEO Confirmation Page, L. Sarounova (Ondrejov, 0.65-m reflector) obtained observations on 11 December showing a tail 20" long in p.a. about 300 deg. C. Hergenrother, Lunar and Planetary Laboratory, reported that a co-added 1200-s R-band image obtained with the 1.54-m Kuiper telescope on 11 December showed a 15" coma and a slightly curved tail > 1' long in p.a. 280 deg. All of the available astrometry (including prediscovery observations on 10 October and 7 December by LINEAR) suggested a perihelion in June at a distance of 1.9 AU. D Tibbets and Gary Hug recovered comet 1999 X1 (Hug-Bell) on 16 July 1999 with the 0.7-m relector at the Farpoint Observatory Eskridge, Kansas. The correction to the perihelion time predicted on MPC 48383 was -0.12 day.
