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 GRB231123.83 (trigger No 722462310,10h 49m 02.40s , +45d 54m 00.0s, R=22.19) errorbox  2915 sec after notice time and 2956 sec after trigger time at 2023-11-23 20:47:41 UT, with upper limit up to  20.7 mag. The observations began at zenith distance = 24 deg. The sun  altitude  is -35.3 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB231123.83 errorbox  76007 sec after notice time and 76047 sec after trigger time at 2023-11-24 17:05:53 UT, with upper limit up to  14.7 mag. The observations began at zenith distance = 68 deg. The sun  altitude  is -31.3 deg. 

The galactic latitude b = 60 deg., longitude l = 167 deg.
