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
121212A.
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
