TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2147 SUBJECT: GRB 030329 OT position DATE: 03/04/18 07:21:37 GMT FROM: Hitoshi Yamaoka at Kyushu U., VSNET-GRB collab. <yamaoka@rc.kyushu-u.ac.jp> H. Yamaoka (Kyushu U), T. Kato, M. Uemura and R. Ishioka (Kyoto U) report: The OT position given in GCN 1994 was obtained with respect to the USN0-A2.0 reference stars (epoch 1955.2). The large apparent proper motions of several stars or the systematic displacements were the main cause of the disagreement noticed by Taylor et al. (GCN 2129) and Henden (GCN 2130). Taking the same procedure as GCN 1994 but using the 2MASS positions, we obtain a refined position of R.A. = 10:44:49.958 +/- 0.005, Decl. = +21:31:17.51 +/- 0.07, which is in good agreement with the radio and optical positions (GCN 2129, 2130).
