(IKI), I. Korobtsev (ISTP) report on behalf of larger GRB follow-up
collaboration:
We observed the field of GRB 161214B (D'Avanzoet al., GCN 20257) with
AZT-33IK telescope of Sayan observatory (Mondy) starting on December, 15
(UT) 13:22:26. We obtained several images in R-filter.
The source previously reported (Malesani et al. GCN 20260; Marshall et
al. GCN 20261) is clearly visible. Preliminary photometry of the source
is following

The photometry includes a catalogued star SDSS J001524.26+072108.5
already mentioned by Malesani et al. (GCN 20260) and Marshall et al.
(GCN 20268). The R magnitude of the star obtained by Lupton
transformations is 18.83 +/- 0.03.
Photometry is based on nearby SDSS-DR9 stars
