TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1668 SUBJECT: GRB021104: possible optical afterglow DATE: 02/11/04 11:00:27 GMT FROM: Weidong Li at UC Berkeley KAIT/LOSS Weidong Li, R. Chornock, S. Jha, and A. V. Filippenko (UCB) report: "We have observed the localization of GRB021104 (HETE Trigger #2434) with the Katzman Automatic Imaging Telescope (KAIT) for several images (with exposure time 20s to 300s unfiltered) starting at 3 Nov 2002 09:47 UT, about 167 minutes after the trigger. Inspection of the images reveals a new object that is not present in DSS II red image of the region. The coordinates of the object are: RA 03:53:47.89 +37:54:28.2 (J2000) The magnitude of the object is about 19.9. We suggest that this object is the possible afterglow of GRB020813."
