- Аннотация: We observed the field of GRB 230812B with the SAO RAS optical telescopes RC-500 and Zeiss-1000 equipped with the CCD photometers. We obtained 90 x 60 sec. images in Rc band with the 0.5-m telescope on August 20, 18:36:51--20:27:56 and 6 x 300 sec. images in Rc band with the 1-m telescope on August 20, 21:09:05--21:43:00 UT. The OT is clearly detected in our stacked frames with the brightness of R = 21.58 +/- 0.11 (t_mid - t0 = 8.0237 days) and R = 21.44 +/- 0.07 (t_mid - t0 = 8.1027 days). This preliminary photometry is based on the nearby SDSS stars; magnitudes are converted using Lupton (2005) equations.
