We began to observe the optical counterpart of the Fermi GRB 130702A
( Singer et al. GCN 14967; Collazzi et al. GCN 14972 )
with Xinglong TNT telescope between 14:10:35 and 15:37:22 UT
on 5 June, 2013. 15*300 sec R-band images were obtained.
The optical counterpart was found with a magnitude of R~19.7 mag,
calibrated by USNO-B 1.0 R2 mag, at the mean time of 3.62 days after the burst.
