Henden (USRA/USNO) reports on behalf of the USNO GRB team:\n\nWe have acquired single R-band images with the NOFS 1.0m\ntelescope from 010922 0654-0807 UT, forming a mosaic that\ncovers nearly all of the HETE/IPN error box (GCN 1097).\n\nInspecting the DPOSS images posted by Fox, et al. (GCN 1098),\nthis region shows a few galaxies, but also a fair amount\nof nebulosity and bright stars.  It is located at galactic\nlongitude 100.5 and latitude -16.8, so not very far out of\nthe galactic plane.  At the same time, the star colors \n(Henden GCN 1100) indicate that there is not a great deal\nof reddening in the field.\n\nIn agreement with Fox, et al. (GCN 1099), we find no obvious\nafterglow candidate down to the DPOSS plate limit.  There are\nseveral probable variable stars and a couple of faint high proper\nmotion objects.",
