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 GRB231124.36 (trigger No 722507896,15h 49m 55.20s , +10d 51m 36.0s, R=2.09) errorbox  49940 sec after notice time and 49975 sec after trigger time at 2023-11-24 22:31:06 UT, with upper limit up to  17.5 mag. The observations began at zenith distance = 80 deg. The sun  altitude  is -19.3 deg. 

The galactic latitude b = 44 deg., longitude l = 21 deg.


Real time updated cover map and OT discovered available here:
