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 GRB190505.82 ( 23h 51m 43.92s , -69d 45m 00.00s, R=30.03) errorbox  21826 sec after trigger time at 2019-05-06 01:41:39 UT, with upper limit up to  18.0 mag. The observations began at zenit distance = 60 deg. The sun  altitude  is -45.2 deg. 

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


Real time updated cover map and OT discovered available here:
