We observed the field of Fermi-GBM GRB 200325B (Fermi GBM team, GCN 
27441) with AZT-33VM 1.5-m telescope of Sayan observatory (Mondy) 
starting on  2020-03-26 (UT) 15:08:10 and and ZTSh 2.6m telescope of 
CrAO starting on 2020-03-26 (UT) 20:11:20. We clearly detected the OT 
discovered by MASTER (Lipunov et al., GCN 27446). Coordinates of the OT 
are (J2000) 11:10:12.54 +27:49:11.7 with uncertainty of 0.5 arcses. The 
R magnitude of the OT is 19.8 +/- 0.15 at 2020-03-26 (UT) 15:08:10.
