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.
