MASTER-IAC  robotic telescope (MASTER-Net:
was pointed to the  INTEGRAL GRB 160629A (Gotz et al., GCN19621) 41 sec 
after GBM trigger at 2016-06-29 22:20:10 UT   by two tubes during Gamma 
Ray active phase (see Gotz et al., GCN19621). We use trigger time 22 19 30 (Gotz et al., GCN19621). 
The OT magnitude is ~ 16.6

MASTER-Kislovodsk  robotic telescope (MASTER-Net: 
located near Kislovodsk was pointed to the  GRB160629A 201 sec
trigger time at 2016-06-29 22:24:11 UT. On 
our first (20s exposure)  image  we  found 1 optical transient within 
INTEGRAL error-box (ra=00 20 16 dec=+77 04 43 r=0.051667) brighter then

The OT found at  position:

00h 19m 27.21s (+-0.09 s =  +-1.4 arcsec ) +76d 58' 01".0 ( +-0.2 arcsec)

(Cf. with TAROT coordinates Klotz  et al., GCN 19622 and Sokolov et
al., GCN 19623).
