GCN Circular 18094
E. Mazaeva (IKI), R. Inasaridze (AAO), Sh. Makandarashvili (AAO), A. Volnova (IKI), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of the Swift GRB 150728A (Krimm et al. GCN 18087) with AS-32 (0.7m) telescope of Abastumani Observatory starting on Jul. 28 (UT) 19:32:14. Within the enhanced XRT error circle (Beardmore et al. GCN 18088) we detected the object coinciding with the object found by FTN (Dichiara et al. GCN 18090). A photometry of the object is following Date UT start t-T0 Filter Exp. OT (mid, days) (s) 2015-07-28 19:32:14 0.30491 None 28*120 20.6+/-0.25 The photometry is based on nearby USNO-B1.0 stars USNO-B.1_id R2 1239-0338943 17.06 1239-0338998 16.69 The photometry could be biased by nearby star. Presently we cannot say nothing about variability of the object and more observation is necessary to confirm/reject the object as afterglow of GRB 150728A.
