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 GRB210715.28 (trigger No 648024201,20h 00m 55.99s , -09d 25m 00.1s, R=34.3833) errorbox 9217 sec after notice time and 9246 sec after trigger time at 2021-07-15 09:17:22 UT, with upper limit up to 17.1 mag. The observations began at zenith distance = 84 deg. The sun altitude is -28.2 deg.
The galactic latitude b = -20 deg., longitude l = 33 deg.
Real time updated cover map and OT discovered available here:
