  "body": "A. Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired BVRcIc all-sky photometry for\na 20x20 arcmin field covering the eastern two thirds of\nthe IPN error box for GRB030204 (Hurley, et. al GCN 1584)\nwith the USNOFS 1.0-m telescope on one photometric night.  Stars\nbrighter than V=12.5 are saturated and should be used with care.\nConditions were clear but with poor seeing; estimated external\nzeropoint error is about 0.03mag.  We have placed the photometric\ndata on our anonymous ftp site:\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb030204.dat\nThe astrometry in this file is based on linear plate solutions\nwith respect to UCAC2.  The external errors are less than 100mas.\n\nWe do not anticipate additional nights of photometry on\nthis field since no afterglow has been detected.  However,\nas with all NOFS calibrations, check the dates on the\nfile prior to final publication to ensure that you have\nthe latest photometry.",
