We continue to observe the optical counterpart of the Fermi GRB 130702A
( Singer et al. GCN 14967; Collazzi et al. GCN 14972 )
with Xinglong TNT telescope at 13:42:16.031 UT on 16 July, 2013
under a bad weather. 6*300 sec R-band images were obtained.
The brightness of the optical afterglow was found with a magnitude
of R~19.6 +/-0.2 mag, calibrated by USNO-B 1.0 R2 mag of the two stars
(Schulze et al. GCN 14978; Pozanenko et al. GCN 15003),
at the mean time of 14.57 days after the burst.
