MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB 200626A ( Fermi GBM team, GCN 28030) errorbox  4639 sec after notice time and 4666 sec after trigger time at 2020-06-26 03:49:18 UT, with upper limit up to  17.8 mag. The observations began at zenith distance = 77 deg. The sun  altitude  is -25.2 deg. 

The galactic latitude b = -11 deg., longitude l = 175 deg.


Real time updated cover map and OT discovered available here:
