GRB 200613A: Kitab and AbAO optical afterglow observations, host galaxy candidate
Abstract
We observed Fermi GRB 200613A (Fermi GBM team, GCN 27926; Bissaldi et al., GCN 27930; Ohno et al., GCN 27931) with Kitab-ISON RC-36 telescope starting on 2020-06-13 (UT) 17:58:33 in Clear filter and AS-32 telescope of Abastumani observatory in R. Within localization area of XRT afterglow (Kennea et al., GCN27936) we detected the only one object in coordinates (J2000) 10:12:10.02 +45:45:13.7 The object is also visible in SDSS *(SDSS12 J101210.07+454512.8*) as a galaxy**with a photometric redshift of z= 0.4745. (We believe that Kann et al. (GCN 27935) observed and reported the same object). We suggest the SDSS galaxy *J101210.07+454512.8* is a host galaxy of GRB 200613A. Preliminary photometry of the source is following Date, UT start, t-T0, Exp., Filter, OT, Err., UL (mid, days) 2020-06-13 17:58:33 0.54057 60*60 CR 19.39 0.20 19.8 2020-06-13 18:16:59 0.55024 50*60 R 19.27 0.07 22.1 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
