GCN Circular 9826
V. Rumyantsev (CrAO), A. Pozanenko (IKI), M. Andreev (Terskol Branch of Institute of Astronomy) report on behalf of larger GRB follow-up collaboration: We observed a field of the INTEGRAL GRB 090817 (Beckmann et al., GCN 9815) with Shajn telescope of CrAO starting on Aug. 17 (UT) 01:07, i.e. ~17 minutes after burst onset. A series of 37 images of 60 s exposure was obtained in R filter. Within XRT error circle of the afterglow (Evans et al., GCN 9819, GCN 9825) we do not detect any new object. The quoted USNO-B1.0 star USNO-B1.0 1341-0096763 (Evans et al., GCN 9819) does not change its brightness within ~0.08 m during our observations. An upper limit of a single frame of 60 s exposure is R~21.5 m. Data reduction is continuing.
