Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired BVRcIc all-sky photometry for\na 11x11 arcmin field centered at the coordinates\nof the SXC error box for the HETE burst GRB030528 (Villasenor\net al., GCN 2261) with the USNOFS 1.0-m telescope on one\nphotometric night.  Stars brighter than V=13.5 are saturated and\nshould be used with care.  We have placed the photometric data\non our anonymous ftp site:\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb030528.dat\nThe astrometry in this file is based on linear plate solutions\nwith respect to UCAC2.  The external errors are less than 100mas.\nHowever, due to the crowding in this galactic field, only\nisolated stars will have decent astrometry or photometry.\n\nAs always, you should check the dates on the .dat file prior to\nfinal publication to get the latest photometry.  We anticipate\none more night of photometry to be acquired during this week.",
