TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5048 SUBJECT: GRB 060502: P60 Afterglow Confirmation DATE: 06/05/02 04:45:42 GMT FROM: S. Bradley Cenko at Caltech S. B. Cenko, E. O. Ofek (Caltech), and D. B. Fox (Penn State) report on behalf of a larger collaboration: We have imaged the field of GRB060502 (La Parola et al., GCN 5047) with the automated Palomar 60-inch telescope. Observations began immediately following astronomical twilight. The UVOT optical candidate is detected in individual 60 s R, g, and i' images and is cleary fading. We therefore confirm this object as the afterglow of GRB060502. We estimate the magnitude of the afterglow to be R ~ 19.8 approximately 40 minutes after the burst trigger (calculated with reference to several nearby USNO-B objects). Observations are continuing.
