A. Volnova (IKI), E. Klunko (ISTP), M. Eselevich (ISTP), I. Korobtsev
(ISTP), A. Pozanenko (IKI) report on behalf of larger GRB follow-up
collaboration:
We observed a field of the GBM GRB 140606B / iPTF 14bfu (Singer et al.,
GCN 16360) with with AZT-33IK telescope of Sayan observatory (Mondy). We
obtained several images on June, 08 (UT) 17:17:29 with exposure of each
frame of 120 s. The optical transient Singer et al., GCN 16360) is well
detected on the stacked image. A photometry is based on nearby USNO-B1.0
stars:

The light curve based on published photometry in r, R and unfiltered
observations (GCNs 16360, 16362, 16367, 16398) can be found in

Based on the lc above one can suggest that a host galaxy of GRB 140606B
may influence on the photometry of the afterglow.
