TITLE: GCN CIRCULAR NUMBER: 9437 SUBJECT: GRB 090529: optical observations DATE: 09/05/30 01:39:58 GMT FROM: Alexei Pozanenko at IKI, Moscow M. Andreev, A. Sergeev (Terskol Branch of Institute of Astronomy), A. Pozanenko (IKI) on behalf of larger GRB follow up collaboration report: We observed the optical afterglow (Xin et al. GCN 9431) of the Swift GRB 090529 (Sakamoto et al. GCN 9430) with the Z-600 telescope of Mt.Terskol observatory in R-filter between (UT) May 29 19:40 -- 20:20. In a combined image (20x120 s) we clearly detect the afterglow at the position (J2000) RA=14 09 52.55 Dec=+24 27 31.2 which is comparable with the afterglow position (Schady et al. GCN 9435, Kann et al. GCN 9436). The combined image finding chart can be found at http://grb.rssi.ru/GRB090529/GRB090529_Z600.JPG The photometry of the afterglow is undergoing.
