Volnova (IKI) report on behalf of IKI-GRB-FuN: 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. Observations and data reduction is ongoing.
