We began to observe GRB 140629A (Lien et al. GCN 16477)
with Xinglong 0.8-m TNT telescope at 14:27:11 (UT) ,
581 sec after the burst. The observations are continued for 1.6 hours.
The optical counterpart reported by (Lien et al. GCN 16477;
Yurkov et al., GCN 16478) was clearly detected in multi-wavelength images.
The brightness of the optical emission is decaying from 14.7mag
to 17.8 mag in R band. The decay slope is estimated to be about 1.2
in our observation epoch.
