RAS), T. Movsesyan (BAO), E. Mazaeva (IKI) report on behalf of of
larger GRB follow-up collaboration:
We observed the field of GRB 180205A (Evans et al., GCN 22381) with
Schmidt-1m telescope of Byurakan Astrophysical Observatory (BAO). We took
several images in r (Sloan)-filter starting on Feb. 08 (UT) 12:54:29. The
afterglow of GRB 180205A (Evans et al., GCN 22381; Zheng et al. GCN 22382;
Bolmer et al. GCN 22383;Tanvir et al. GCN 22384; Volnova et al. GCN 22387;
Falcon et al. GCN 22380; Xin et al. GCN 22392; Zhu et al. GCN 22395; Emery
et al. GCN 22396; Im et al., GCN 22397; Oksanen et al. 22401; Mazaeva et
al., GCN 22403) is clearly detected in a stacked image. Preliminary
photometry is following.
