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 on the HETE coordinates\n(trigger 11553) for GRB040825A\nwith the USNOFS 1.0-m telescope on one photometric night.\nStars 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/grb040825a.dat\nThe astrometry in this file is based on linear plate solutions\nwith respect to UCAC2.  The external errors are less than 100mas.\nThe estimated external photometric error is about 0.03mag\nand will be improved with additional calibration nights\nif an afterglow is discovered.\n\nAs always, you should check the dates on the .dat file prior to\nfinal publication to get the latest photometry.  There is\na README file on the ftp directory to give you information\nabout the procedures used to calibrate these fields.",
