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 GRB200125.86 (trigger No 601677816,00h 29m 48.00s , +64d 41m 24.0s, R=1) errorbox  48 sec after notice time and 95 sec after trigger time at 2020-01-25 20:45:06 UT, with upper limit up to  19.2 mag. The observations began at zenith distance = 57 deg. The sun  altitude  is -61.0 deg. 

MASTER-IAC robotic telescope  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB200125.86 errorbox  108 sec after notice time and 155 sec after trigger time at 2020-01-25 20:46:06 UT, with upper limit up to  19.1 mag. The observations began at zenith distance = 48 deg. The sun  altitude  is -28.4 deg. 

MASTER-Amur robotic telescope  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB200125.86 errorbox  108 sec after notice time and 3849 sec after trigger time at 2020-01-25 21:47:40 UT, with upper limit up to  17.5 mag. Observations started at twilight.  The observations began at zenith distance = 63 deg. The sun  altitude  is -13.7 deg. 

The galactic latitude b =  2 deg., longitude l = 121 deg.
