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 GRB210807.96 (trigger No 1064421,09h 34m 12.24s , -51d 24m 32.4s, R=0.05) errorbox  55 sec after notice time and 171 sec after trigger time at 2021-08-07 22:59:59 UT, with upper limit up to  17.0 mag. Observations started at twilight.  The observations began at zenith distance = 66 deg. The sun  altitude  is -12.4 deg. 

The galactic latitude b =  0 deg., longitude l = 275 deg.


Real time updated cover map and OT discovered available here:
