MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB200126.47 (trigger No 601729856,03h 57m 52.80s , -59d 37m 12.0s, R=12.33) errorbox  27066 sec after trigger time at 2020-01-26 18:41:58 UT, with upper limit up to  19.4 mag. Observations started at twilight.  The observations began at zenith distance = 23 deg. The sun  altitude  is -11.7 deg. 

MASTER-IAC robotic telescope  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB200126.47 errorbox  30219 sec after trigger time at 2020-01-26 19:34:31 UT, with upper limit up to  18.2 mag. Observations started at twilight.  The observations began at zenith distance = 78 deg. The sun  altitude  is -12.8 deg. 

The galactic latitude b = -45 deg., longitude l = 272 deg.
