We observed the Swift GRB 140629A field (Lien et al., GCNC 16477) using
1.04m ST telescope at ARIES Nainital. Observations were started at 17:40:59
UT on 2014-06-29 (approximately 3.4 h after the burst). Several frames
with an exposure time of 300 s each in R_c and I_c bands were obtained in
good sky conditions.
The optical counterpart of GRB 140629A (Lien et al., GCNC 16477;
Yurkov et al., GCNC 16478; Bikmaev et al., GCNC 16482; Masi, GCNC
16483; ) is clearly detected in each individual frames.
Preliminary photometry is following:

The photometry was performed in comparison to nearby USNO stars.
