A. Volnova (IKI), N. Tungalag (Research Centre of Astronomy and Geophysics
MAS ) V. Voropaev (KIAM), I.Molotov (KIAM), A. Pozanenko (IKI) report on
behalf of larger GRB
follow-up collaboration:
We observed the field of the Swift GRB 140129A (Melandri et al., GCN 15760)
on Jan., 29 with ORI-40 telescope of Khureltogot observatory (Mongolia).
We took
several unfiltered images of 60 s exposure. Within enhanced XRT error
circle (Evans et al., GCN 15764) we do not detect the optical afterglow
(Melandri et al., GCN 15760).
Details of the photometry are following:
UT start t-T0 Filter Exp. OT UL (3 sigma)
(mid, days) (s)
12:02:22 0.38515 None 68x60 n/d 20.0
The photometry is based 3 SDSS stars, R (gri -> R transformations by
Lupton 2005):
SDSS id R
J023133.01-013533.5 18.121
J023122.45-013411.0 18.797
