(IKI) report on behalf of larger GRB follow-up collaboration:
We observed a field of the Swift GRB 140606A (Stroh et al., GCN 16353)
with AS-32 (0.7m) telescope of Abastumani Observatory starting on June,
06 (UT) 18:16:50. We obtained several unfiltered frames with exposure of
each frame of 120 s. Within the BAT ground-calculated position (Cummings
et al., GCN 16354) we do not detect evident variable source.
The details of the photometry are the following:
