GRB 200806A: AbAO optical upper limit
Abstract
We observed the field of Swift GRB 200806A (Ambrosi et al., GCN 28211) also registered by AstroSat CZTI (Gupta et al., GCN 28216) with AS-32 (0.7m) telescope of Abastumani Observatory starting on 2020-08-06 (UT) 23:42:53. We do not detect any object within the enhanced XRT position error circle (Beardmore et al., GCN 28214). Preliminary photometry of the field is following. Date UT start t-T0 Filter Exp. OT Err. UL (mid, days) (s) 2020-08-06 23:42:53 0.36498 R 63*60 n/d n/d 21.0 The photometry is based on nearby USNO-B1.0 stars USNO-B1.0_id R2 1270-0058216 15.48 1270-0058260 14.22 1270-0058260 14.98 1271-0065622 15.31
