GCN Circular 28328
A. S. Moskvitin, V. N. Aitov (SAO RAS) on behalf of GRB follow-up team report. We observed the field of the GRB 200829A (Siegel et al., GCN 28307) with Zeiss-1000 (1-m telescope of SAO RAS) equipped with Multi-Mode Photometer-Polarimeter (MMPP) on August 30. We obtained 5 x 300 sec. frames in Rc band and similar sequence in Ic band. The OT (Siegel et al., GCN 28307; Pozanenko et al., GCN 28308; Kuin and Siegel, GCN 28311; Lipunov et al., GCN 28315; Vinko et al., 28316; Hentunen and Nissinen, GCN 28318; Zhu et al., GCN 28324) is clearly detected in individual images as well as stacked frames with the brightness of R = 20.37 +/- 0.13 (T_mid - T0 = 1.1492 days), I = 20.14 +/- 0.10 (T_mid - T0 = 1.1662 days). Preliminary photometry is based on R2 and I magnitudes of the same nearby USNO-B1 stars (Moskvitin and Aitov, GCN 28322).
