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 200619B ( Fermi GBM team, GCN 27986) errorbox  33291 sec after notice time and 33333 sec after trigger time at 2020-06-19 21:04:16 UT, with upper limit up to  17.6 mag. Observations started at twilight.  The observations began at zenith distance = 73 deg. The sun  altitude  is -12.6 deg. 

The galactic latitude b = 18 deg., longitude l = 303 deg.
