TITLE: GCN CIRCULAR NUMBER: 27937 SUBJECT: GRB 200613A: Kitab and AbAO optical afterglow observations, host galaxy candidate DATE: 20/06/14 08:21:00 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Pozanenko (IKI), S. Belkin (IKI), A. Novichonok (Petrozavodsk State University, KIAM), R. Ya. Inasaridze (AbAO), V.R. Ayvazian (AbAO),�� G. V.�� Kapanadze (AbAO),�� E. Mazaeva�� (IKI), A. Volnova (IKI), I. Molotov (KIAM), Sh. Ehgamberdiev (UBAI) report on behalf of IKI-GRB-FuN: 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.
