- Аннотация: We observed the field of GRB 230812B (Fermi GBM Team, GCN 34386; Scotton et al., GCN 34392; Page et al. GCN 34394; Kuin et al., GCN 34399; Casentini et al., GCN 34402) with the 1-m telescope of SAO RAS Zeiss-1000 equipped with the CCD photometer. We obtained 6 x 300 sec. images in Rc band on August 19, 18:11:41--18:45:30 UT. The object is clearly detected in our stacked frame with the brightness of R = 21.8 +/- 0.1 (t_mid - t0 = 6.9794 days). This preliminary photometry is based on the nearby SDSS stars; magnitudes are converted using Lupton (2005) equations.
