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). We obtained 4 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) is clearly detected
with the brightness R = 17.84 +/- 0.09 (T_mid - T0 = 4.587 h),
I = 17.65 +/- 0.09 (T_mid - T0 = 4.204 h).
Preliminary photometry is based on R2 and I magnitudes
of nearby USNO-B1 stars.
