GRB 200613A: continued AbAO optical afterglow observations

We continue observations of Fermi GRB 200613A (Fermi GBM team, GCN 27926; Bissaldi et al., GCN 27930; Ohno et al., GCN 27931) with AS-32 telescope of Abastumani observatory in R-filter. The afterglow (e.g., Kann et al., GCN 27935; Kennea et al., GCN 27936; Pozanenko et al., GCN 27937; Izzo et al., GCN 27939; Zhu et al., GCN 27943) is detected in a stacked image. Preliminary photometry of the afterglow is following Date, UT start, t-T0, Exp., Filter, OT, Err., UL (mid, days) 2020-06-15 17:44:15 2.53029 49*60 R 20.47 0.11 21.9 The photometry is based on nearby SDSS DR12 stars SDSS-DR12_id R(Lupton) J101149.76+454320.7 12.404 J101245.45+455119.1 13.328
