report on behalf of larger GRB follow-up collaboration:
We observed the field of GRB 130925A (Lien, et al., GCN 15246) with
AZT-8 (0.7m) telescope of Gissar observatory in R filter starting on
Sep. 25 (UT) 22:15. We do not detect optical afterglow (Sudilovsky et
al., GCN 15247). A preliminary photometry of combined image is following
T_start T0+ Filter, Exposure, OT, UL(3 sigma)
(UT) (mid, d) (s)
2013-09-25T22:16:55 0.7766 R 60x60 n/d 19.9
The photometry is based on the reference star USNO-B1.0 0638-0038928
RA 02:45:02.36 Dec -26:10:50.2 (J2000), assuming R = 17.07
