C. W. Hergenrother (Lunar and Planetary Laboratory, Arizona, USA) discovered this comet with the 0.41-m f/3 Schmidt telescope in the course of the Catalina Sky Survey on 4 February 2000. He determined the magnitude as 17.1. One of the four CCD images revealed a tail extending 11 arc seconds toward PA 300°. Prediscovery observations were found on Lincoln Laboratory Near- Earth Asteroid Research (LINEAR) project images made on 4 and 8 January, with nuclear magnitudes ranging from 18.7 to 19.4.
