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 GRB210714.33 (trigger No 647942198,20h 46m 43.20s , -52d 12m 36.0s, R=1.38) errorbox 150 sec after notice time and 181 sec after trigger time at 2021-07-14 07:59:34 UT, with upper limit up to 19.5 mag. The observations began at zenith distance = 34 deg. The sun altitude is -44.8 deg.
The galactic latitude b = -39 deg., longitude l = 346 deg.
Real time updated cover map and OT discovered available here:
