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) was pointed to the SWIFT GRB210725.16 (trigger No 1061511,14h 21m 27.12s , -01d 10m 37.2s, R=0.05) errorbox  78 sec after notice time and 169 sec after trigger time at 2021-07-25 03:49:52 UT, with upper limit up to  16.5 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -73.8 deg. 

The galactic latitude b = 54 deg., longitude l = 345 deg.


Real time updated cover map and OT discovered available here:
