- Аннотация: We observed the field of the GRB 230805B (Cenko et al., GCNC #34339) with the 1-m telescope of SAO RAS Zeiss-1000 equipped with the Multi-Mode Photometer-Polarimeter (MMPP). We obtained 4 x 300 sec. exposures in Rc band on August 5, 17:50:15--18:11:48 UT. Within the XRT error circle we marginally detected a single object (possible OT) with coordinates (Epoch = 2000.0): R.A. = 13:50:58.2, Dec. = +31:11:28.6 (+/- 0".5) and brightness about R = 22.7 +/- 0.3 (t_mid - t0 = 6.61 hours). This preliminary photometry is based on the nearby SDSS stars; magnitudes are converted using Lupton (2005) equations.
