TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1423
SUBJECT: GRB020603, BVRcIc field observations
DATE:    02/06/11 20:16:11 GMT
FROM:    Arne A. Henden at USNO/USRA  <aah@nofs.navy.mil>

A. Henden (USRA/USNO) reports on behalf of the USNO GRB team:

We have acquired BVRcIc all-sky photometry for
an 11x11 arcmin field centered at the IPN coordinates
for the short/hard burst GRB020603 (Hurley et al., GCN 1409)
with the USNOFS 1.0-m telescope on one photometric night.  Stars
brighter than V=14.0 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/grb020603.dat
The astrometry in this file is based on linear plate solutions
with respect to UCAC2.  The external errors are less than 100mas.
The photometry has potential zeropoint error of about 0.02mag.
