TITLE: GCN CIRCULAR NUMBER: 17468 SUBJECT: GRB 150213B: AAO optical observations DATE: 15/02/14 07:06:15 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Pozanenko (IKI), R. Inasaridze (AAO), E. Mazaeva (IKI), A. Volnova (IKI), Molotov (KIAM), report on behalf of larger GRB follow-up collaboration: We observed the field of the Swift GRB 150213B (Pagani et al., GCN 17464) with AS-32 (0.7m) telescope of Abastumani Observatory. We obtained several unfiltered images starting on Feb. 13 (UT) 23:24:58 and ending Feb. 14 (UT) 01:06:30. In the first single images of 120 s exposure we clearly detect the optical afterglow (Pagani et al., GCN 17464; Kann et al., GCN 17465; Malesani et al., GCN 17467). Preliminary photometry of the afterglow is 19.7m (at 54 minutes after burst trigger) in comparison with nearby USNO-B1.0 stars (R2 mags). Data receiving and reduction is ongoing.
