V. Rumyantsev, S. Artemenko (CrAO), A. Pozanenko (IKI), A. J. Castro-Tirado
(IAA-CSIC Granada), report on behalf of larger GRB follow-up collaboration:
We observed the field of SGR 0501+4516 (Holland et al. GCN 8112, Barthelmy
et al. GCN 8113), in I band on August 26-28 with Shajn telescope of CrAO.
The observation epochs are 2008-08-26T23:17:51 -- 2008-08-27T00:05:51 and
2008-08-27T23:27:32 -- 2008-08-28T00:31:32. We do not detect NIR/optical
counterpart of SGR 0501+4516 (Tanvir et al, GCN 8126, Rea et al, GCN 8159,
Fatkhullin et al, GCN 8160) in the first epoch, while in the second epoch
(Aug. 27.9993) one may suggest a presence of counterpart. Upper limits of
combined images are following:
Mean epoch, Exposure, UL (3sigma)

Aug. 27.9993 60x60 23.6
