Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired preliminary shallow BVRc all-sky photometry for\nan 11x11 arcmin field that covers the error box for GRB000508B\nwith the USNOFS 1.0-m telescope on one photometric night.\nStars brighter than V=12 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/grb000508b.dat\nThe current photometry has a potential external zero-point\nerror of about two percent.  The astrometry in this file\nis based on linear plate solutions with respect to USNO-A2.0.\nThe internal errors are less than 100mas.\n  Further calibration of this field will be performed if\nan optical afterglow is identified.",
