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 GRB190726.84 (trigger No 585864875, 22h 50m 43.20s , -55d 58m 48.00s, R=2.43) errorbox  546 sec after notice time and 575 sec after trigger time at 2019-07-26 20:24:05 UT, with upper limit up to  20.7 mag. The observations began at zenit distance = 55 deg. The sun  altitude  is -56.0 deg. 

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


Real time updated cover map and OT discovered available here:
