MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB200130.25 (trigger No 602056641,21h 57m 09.60s , -65d 55m 48.0s, R=1.69) errorbox  3000 sec after notice time and 3031 sec after trigger time at 2020-01-30 06:47:47 UT, with upper limit up to  18.3 mag. The observations began at zenith distance = 81 deg. The sun  altitude  is -33.3 deg. 

The galactic latitude b = -43 deg., longitude l = 325 deg.
