Maslennikova (SAO RAS)\nreport on behalf of the GRB follow-up team.\n\nWe observed the field of Swift GRB 231110A (D'Elia et al., GCN #34977)\nwith the 1-m telescope of SAO RAS equipped with the CCD photometer.\nWe obtained 8 x 300 sec. images in Rc band on November 10,\n22:09:05--22:55:32 UT (t_mid - T0 = 1.21224 hours).\n\nFollowing the non-detection of OT by MASTER team (Lipunov et al.,\nGCN #34978) we also did not detect any significant source within\nthe probable XRT error circle (Beardmore et al., GCN #34986)\ndown to the limiting magnitude R_lim = 22.9. We should note\nthe presence of the first object mentioned by Sun et al. (GCN #34979)\nnear the XRT error circle. The brightness of this object is\nR = 22.50 +/- 0.24.\n\nPreliminary photometry is based on nearby USNO-B1 stars (R2 mag).\nMagnitudes are not corrected for MW extinction.\n",
