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 200530A ( Fermi GBM team, GCN 27861) errorbox  592 sec after notice time and 619 sec after trigger time at 2020-05-30 00:54:29 UT, with upper limit up to  16.1 mag. The observations began at zenith distance = 75 deg. The sun  altitude  is -40.2 deg. 

The galactic latitude b =  9 deg., longitude l = 125 deg.


Real time updated cover map and OT discovered available here:
