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 GRB 210501A ( Fermi GBM team, GCN 29919) errorbox  228 sec after notice time and 264 sec after trigger time at 2021-05-01 04:59:25 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -72.9 deg. 

The galactic latitude b = -45 deg., longitude l = 310 deg.


Real time updated cover map and OT discovered available here:
