Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired BVRcIc all-sky photometry for\nan 11x11 arcmin field centered at the IPN coordinates\nfor the short/hard burst GRB020603 (Hurley et al., GCN 1409)\nwith the USNOFS 1.0-m telescope on one photometric night.  Stars\nbrighter than V=14.0 are saturated and should be used with care.\nWe have placed the photometric data on our anonymous ftp site:\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb020603.dat\nThe astrometry in this file is based on linear plate solutions\nwith respect to UCAC2.  The external errors are less than 100mas.\nThe photometry has potential zeropoint error of about 0.02mag.",
