TITLE: GCN GRB OBSERVATION REPORT NUMBER: 988 SUBJECT: GRB010214, field photometry DATE: 01/02/25 01:14:33 GMT FROM: Arne A. Henden at USNO/USRA A. Henden (USRA/USNO) reports on behalf of the USNO GRB team: We have acquired preliminary BVRcIc all-sky photometry for the field of GRB010214 with the USNOFS 1.0-m telescope on one photometric night with poor seeing. This 11x11arcmin field includes the proposed counterpart and extends to approximately V=20. All stars brighter than V=14 are saturated and should be used with care. We have placed the photometric data on our anonymous ftp site: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb010214.dat The current photometry has a potential external zero-point error of about two percent that needs to be added in quadrature to the Poisson errors given in the datafile. The astrometry in this file is based on linear plate solutions with respect to USNO-A2.0. The internal errors are less than 100mas. At least two additional nights of photometry will be added to the data file when weather conditions permit.
