Pozanenko(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the field of the Swift GRB 140108A (Racusin et al., GCN
15699) with AZT-33IK telescope of Sayan observatory (Mondy) starting
Jan., 08 (UT) 17:24:55. We obtained several images in R-filter with
exposure of 20,60 and 180 seconds. Within the enhanced XRT circle (Evans
et al., GCN 15700) we detected optical afterglow (Gorbovskoy et al.,
GCN 15701; Gorosabel et al., 15702) The position of the afterglow
coincids with previously reported (Gorbovskoy et al., GCN 15701; Strobl
et al., 15703). At (UT) 17:32, i.e. ~13.5 min. after GRB trigger the
R-magnitude of the afterglow is ~19.2.
