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 GRB240112.74 (trigger No 726774492,14h 06m 16.08s , -25d 12m 00.0s, R=12.97) errorbox  9695 sec after notice time and 9708 sec after trigger time at 2024-01-12 20:29:55 UT, with upper limit up to  18.6 mag. The observations began at zenith distance = 77 deg. The sun  altitude  is -42.3 deg. 

The galactic latitude b = 34 deg., longitude l = 324 deg.


Real time updated cover map and OT discovered available here:
