A. Pozanenko (IKI), A. Sergeev (Institute of Radio Astronomy of NASU), 
A. Volnova (SAI MSU), O. Burhonov (UBAI), I. Molotov (KIAM) report on 
behalf GRB follow-up collaboration:

We observed  the field of Swift  GRB 121212A  (Grupe et al., GCN 
14064) with AZT-22 telescope of Maidanak observatory starting on Dec. 12 
(UT) 20:51:02 under mean seeing (FWHM) of about 1 arcsec. Totally we 
obtained 6 images of 600 s exposure in R  filter. At the position of the 
OT of GRB 121212A (Kuin et al., GCN  14069;  Perley and Horesh, GCN 
14070; Elenin et al., GCN 14071) we marginally detected an extended 
object. If it will be confirmed the object might be a host galaxy of GRB 

A preliminary photometry of the object:

T0+        Filter,  Exposure,   OT
(mid, d)            (s)

0.60088     R       6x600       23.0 �� 0.35

is based on USNO-B1.0 nearby stars:

USNO-B1.0 1680-0064718 11:51:09.04 +78:00:39.9 R2 = 16.34
USNO-B1.0 1680-0064713 11:51:05.10 +78:02:00.1 R2 = 19.35
