Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired a second night of BVRcIc all-sky photometry for\nan 11x11 arcmin field that covers the northern 60 percent of the\nerror box for GRB000630 with the USNOFS 1.0-m telescope.\nWe have placed the revised photometric data on our anonymous ftp site:\nftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb000630.dat\nThe current photometry has a potential external zero-point\nerror of less than 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\nIn particular, the position/magnitudes of the two stars\nmentioned in Halpern, et al. (GCN 745) have the revised values of:\n\n    Star       RA(2000)    Dec(2000)        R        I \n    -----------------------------------------------------\n     A       14 47 01.67  +41 16 16.9     17.43    16.87\n     B       14 46 59.26  +41 15 52.2     18.60    18.14\n    -----------------------------------------------------",
