Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired shallow BVRcIc all-sky photometry for\na 20x20 arcmin field centered at the IPN coordinates\nfor GRB021201 (Hurley et al., GCN 1719) with the USNOFS 1.0-m\ntelescope on one photometric night.  Stars\nbrighter than V=13.0 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/grb021201.dat\nThe astrometry in this file is based on linear plate solutions\nwith respect to UCAC2.  The external errors are less than 100mas.\n\nIf an afterglow is discovered, we will extend this calibration\nwith additional nights to ensure against a systematic zeropoint error,\nand to include U-band measures.  You should check the dates on\nthe .dat file prior to final publication to get the latest photometry.",
