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) started inspect of the Fermi GRB231118.94 (trigger No 722039659,23h 15m 43.20s , +33d 34m 12.0s, R=1) errorbox  43915 sec after notice time and 43950 sec after trigger time at 2023-11-19 10:46:45 UT, with upper limit up to  16.0 mag. Observations started at twilight.  The observations began at zenith distance = 26 deg. The sun  altitude  is -14.1 deg. 

The galactic latitude b = -25 deg., longitude l = 102 deg.
