Pozanenko (IKI) report on behalf of \nlarger GRB follow-up collaboration:\n\nWe observed the field of the Swift GRB 150728A (Krimm et al. GCN 18087) \n  with AS-32 (0.7m) telescope of Abastumani Observatory starting on Jul. \n28 (UT) 19:32:14.  Within the enhanced XRT error circle (Beardmore et \nal. GCN 18088) we detected the object coinciding with the object found \nby FTN (Dichiara et al. GCN 18090).  A photometry of the object is following\n\nDate       UT start    t-T0     Filter  Exp.

Presently we cannot say \nnothing about variability of the object and more observation is \nnecessary to confirm/reject the object as afterglow of GRB 150728A.",
