We observed the field of Swift GRB 231215A (D'Avanzo et al., GCN 35343; Evans et al., GCN 35345) with AZT-33IK telescope of Mondy observatory in R-filter starting on 2023-12-15 (UT) 11:17:39. Preliminary photometry of the fist immaes reveals a new bright source within XRT error circle (Evans et al., GCN 35345)

The photometry is based on nearby USNO-B1.0 R2 stars.
We also may suggest that GCN 35347 (Lipunov et al.) refer to the afterglow of GRB 231215A.
