TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1859 SUBJECT: GRB020819: Kiso R and I band observations DATE: 03/02/05 15:27:17 GMT FROM: Yuji Urata at RIKEN Y. Urata, K. Tarusawa, T. Soyano on behalf of the Kiso GRB team: "We have observed the field of GRB020819 with the KISO observatory 1.05m schmidt telescope starting at Aug 19.747 UT (2.9 hour after the burst). We obtained R and I band data with 300 sec x 4 frames and three 300 sec x 3 frames respectively. We could not identify any stellar object at the position of radio afterglow (RA) reported by Frail & Berger (GCN 1842). The R band limiting magnitude is 18.9 mag. It was estimated by comparison with field photometry ( Dr. Levan ; private communication). For I band data, because there are no field photometry, we can not estimate the limiting magnitude. Following the DSS-II red image (Plate ID = A0J7), we found that a faint object is located at near the RA position. The coordinate is RA=23:27.20 DEC=+06:15:53 measured by using WCS of the image. We thank to Dr. Levan for R band field photometry." This message may be cited.
