MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240106.02 (trigger No 726194053,00h 31m 50.40s , +53d 41m 24.0s, R=1.7) errorbox  298 sec after notice time and 333 sec after trigger time at 2024-01-06 00:39:42 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 77 deg. The sun  altitude  is -48.9 deg. 

The galactic latitude b = -9 deg., longitude l = 120 deg.
