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
The photometry of the afterglow is undergoing.
