MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB191225.73 (trigger No 598988276,09h 43m 12.00s , -07d 10m 48.0s, R=2.84) errorbox  538 sec after notice time and 571 sec after trigger time at 2019-12-25 17:47:23 UT, with upper limit up to  17.0 mag. The observations began at zenith distance = 59 deg. The sun  altitude  is -52.4 deg. 

The galactic latitude b = 33 deg., longitude l = 244 deg.
