TITLE: GCN CIRCULAR NUMBER: 13556 SUBJECT: GRB 120802A: optical uper limit in ISON-NM observatory DATE: 12/08/02 10:06:08 GMT FROM: Alexei Pozanenko at IKI, Moscow L. Elenin (KIAM), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of GRB 120802A (Holland et al., GCN 13555) with 0.45-m telescope Ïf ISON-NM observatory starting on Aug. 02 (UT) 08:13:18, i.e. 12.5 minutes after burst trigger. We took several unfiltered images of 30 s exposure. We do not detect any source within XRT error circle (Holland et al., GCN 13555) in any co-added frames. The preliminary photometry of co-added frames is based on the USNO-B1.0 (R2) nearby stars: T_start, Exposure, OT, Upper Limit (3sigma) (UT) (s) 08:13:18 10x30 n/d 17.5 08:13:18 20x30 n/d 17.7 08:13:18 29x30 n/d 18.1 Observations are continued.
