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 GRB231122.53 (trigger No 722349867,07h 13m 48.00s , -05d 32m 24.0s, R=3.82) errorbox  14285 sec after notice time and 14321 sec after trigger time at 2023-11-22 16:43:04 UT, with upper limit up to  17.2 mag. The observations began at zenith distance = 68 deg. The sun  altitude  is -59.1 deg. 

The galactic latitude b =  3 deg., longitude l = 221 deg.
