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 GRB200612.20 (trigger No 613630183,18h 53m 52.08s , -36d 55m 01.2s, R=34.25) errorbox 25 sec after trigger time at 2020-06-12 04:50:04 UT, with upper limit up to  18.9 mag. The observations began at zenith distance = 33 deg. The sun  altitude  is -81.4 deg. 

The galactic latitude b = -17 deg., longitude l = 360 deg.


Real time updated cover map and OT discovered available here:
