MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB190622.37 (trigger No 582886211,  9h 52m 57.60s , -33d 50m 24.00s, R=14.45) errorbox  34122 sec after trigger time at 2019-06-22 18:18:48 UT, with upper limit up to  18.0 mag. The observations began at zenit distance = 47 deg. The sun  altitude  is -32.2 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.


Real time updated cover map and OT discovered available here:
