(KIAM), report on behalf of larger collaboration:
We observed the field of GRB 140930B (De Pasquale et al., GCN 16857)
with Santel-400AN telescope of ISON-Kislovodsk observatory starting on
Sep. 30 (UT) 19:52:24, i.e. ~10.5 minutes after burst trigger. We took
30 unfiltered images of 120 s exposure. In the enhanced XRT position
(Evans et al. GCN 16859) we do not detect the optical candidate (Tanvir
et al., GCN 16861). A preliminary upper limit of the first image is
19.5m (at mid time (UT) 19:53:24) and is based on nearby USNO-B1.0
stars, R2 magnitudes.
