GCN Circular 34987
A. S. Moskvitin and O. A. Maslennikova (SAO RAS) report on behalf of the GRB follow-up team. We observed the field of Swift GRB 231110A (D'Elia et al., GCN #34977) with the 1-m telescope of SAO RAS equipped with the CCD photometer. We obtained 8 x 300 sec. images in Rc band on November 10, 22:09:05--22:55:32 UT (t_mid - T0 = 1.21224 hours). Following the non-detection of OT by MASTER team (Lipunov et al., GCN #34978) we also did not detect any significant source within the probable XRT error circle (Beardmore et al., GCN #34986) down to the limiting magnitude R_lim = 22.9. We should note the presence of the first object mentioned by Sun et al. (GCN #34979) near the XRT error circle. The brightness of this object is R = 22.50 +/- 0.24. Preliminary photometry is based on nearby USNO-B1 stars (R2 mag). Magnitudes are not corrected for MW extinction.
