A. Volnova (SAI MSU), K. Naumov, V. Kouprianov, A. Devyatkin (Pulkovo 
Observatory), A. Pozanenko (IKI)  report on behalf of larger GRB follow-up 
collaboration:

We observed   the field of the Swift GRB 090529  (Sakamoto et al. GCN 9430) 
with MTM-500 (0.5m) telescope of  Kislovodsk solar station (43d 44.77' N, 
42d 31.42' W) of the Pulkovo observatory  in two series in R-filter starting 
May 29 (UT) 19:58. We do not detect optical afterglow
(Xin et al. GCN 9431). The upper limits  of combined images based on 
USNO-B1.0 are following:

T0+     Filter, Exposure, mag.,
(d)             (s)

0.2817   R       60x60     > 19.3
0.3324   R       55x60     > 19.4
