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 200615A ( Fermi GBM team, GCN 27947) errorbox 13375 sec after notice time and 13402 sec after trigger time at 2020-06-15 09:43:27 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 77 deg. The sun altitude is -22.4 deg.
The galactic latitude b = -42 deg., longitude l = 175 deg.
Real time updated cover map and OT discovered available here:
