(IKI) report on behalf of larger GRB follow-up collaboration:
We observed the Swift GRB 140703A (Kocevski et al., GCN 16503) with
AS-32 (0.7m) telescope of Abastumani Observatory starting on July, 07
(UT) 23:27:06. We obtained several unfiltered frames under exellent
weather with exposure of each frame of 120 s. The optical afterglow
(Cunniffe et al. GCN16504) is well detected on the stacked image.
Details of a photometry of the pi-redsifted GRB 140703A (Castro-Tirado
et al., GCN 16505) are following:

2014-07-03 23:27:06 0.97235 None 23*120 21.27 +/- 0.08
The photometry is based on following SDSS stars and gri -> R
transformation (Lupton, 2005)
