MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the Integral GRB231129.21 (trigger No 10436,21h 10m 18.76s , +41d 31m 39.2s, R=0.0528333) errorbox  17767 sec after notice time and 17792 sec after trigger time at 2023-11-29 10:02:31 UT, with upper limit up to  15.1 mag. Observations started at twilight.  The observations began at zenith distance =  9 deg. The sun  altitude  is -8.7 deg. 

The galactic latitude b = -5 deg., longitude l = 85 deg.
