Molotov (KIAM) report on behalf of  GRB IKI FuN:\n\nWe observed the field of Swift/BAT-GUANO position (DeLaunay et al., GCNs \n28013, 28016) of  GRB 200623A (Fermi GBM team,  GCN 28011; Veres et al., \nGCN 28019) with AS-32 (0.7m) telescope of Abastumani Observatory \nstarting on 2020-06-23 (UT) 18:46:58.  We  detected only one object \nwithin the XRT #2 source localization \n(https://www.swift.ac.uk/ToO_GRBs/00021005/). The source is not \npresented in SDSS DR12. We suggest the object could be afterglow of  GRB \n200623A. However at this time we cannot confirm variability of the \nobject.   Preliminary photometry of the object is following.\n\nDate       UT start  t-T0    Filter Exp.  OT    Err.
