TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1031 SUBJECT: GRB010324, revised field photometry DATE: 01/03/30 15:43:58 GMT FROM: Arne A. Henden at USNO/USRA A. Henden (USRA/USNO) reports on behalf of the USNO GRB team: We have obtained a second night of photometry with the NOFS 1.0m telescope for the field of GRB010324. The revised BVRcIc photometry file can be found at ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb010324.dat The quality of this file is still below our normal standards, but is good to about 0.03mag for all magnitudes and colors. No further revisions are anticipated unless an optical transient is discovered in this field. The USNO-A2.0 star mentioned in Bloom et al. (GCN1024) lies just to the south of this calibration field and so is not included in the file. Arne
