  "body": "A. Henden (USRA/USNO) and S. Levine (USNO) report on behalf\nof the USNO GRB team:\n\nWe have measured the two high signal/noise Ic images\nacquired on the Strand 1.55m astrometric telescope at NOFS\non 021005 UT.  Using 23 UCAC2 stars on each frame,\nwe derive the following accurate position for the optical\nafterglow of GRB021004:\n\n  00:26:54.674  +18:55:41.59  J2000\n\nwith approximately 50mas external error in each coordinate.\nThis is in good agreement with the coordinates given\nby Fox, et al. (GCN 1564)."
