Found on the evening of March 21 2000 while searching archive data from the LASCO C3 instrument on FITS images taken on May 11 1999. The comet was seen moving away from the Sun, getting brighter then fading, it could be followed on the May 12th images as well. Doug Biesecker also located the comet on C2 frames on the 10th.
