report on behalf of larger GRB follow-up collaboration:
We observed the field of the Swift GRB 130606A (Ukwatta et al., GCN
14781) with AZT-11 telescope of CrAO observatory starting on June 06
(UT) 21:59:60. We took several images in R-filter of 180 s exposure. The
afterglow (Jelinek et al., GCN 14782; Xu et al., GCN 14783; Nagayama et
al., GCN 14784) is not detected in a combined image. A photometry is
based on the same SDSS stars we used in GCN 14806:
Start T0+, Filter Exposure, OT, UL (3 sigma)
