Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired preliminary BVRcIc all-sky photometry for\nthe field of GRB010214 with the USNOFS 1.0-m telescope on one\nphotometric night with poor seeing.  This 11x11arcmin field includes\nthe proposed counterpart and extends to approximately V=20.\nAll stars brighter than V=14 are saturated and should be used\nwith care.  We have placed the photometric data on our\nanonymous ftp site:\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb010214.dat\nThe current photometry has a potential external zero-point\nerror of about two percent that needs to be added in\nquadrature to the Poisson errors given in the datafile.\nThe astrometry in this file is based on linear\nplate solutions with respect to USNO-A2.0. The internal errors\nare less than 100mas.\n\nAt least two additional nights of photometry will be added to the data\nfile when weather conditions permit.",
