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 201109A ( Fermi GBM team, GCN 28868) errorbox 533 sec after notice time and 585 sec after trigger time at 2020-11-09 02:40:50 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 69 deg. The sun altitude is -61.5 deg.
The galactic latitude b = 27 deg., longitude l = 235 deg.
Real time updated cover map and OT discovered available here:
