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 GRB190726.75 (trigger No 585856427, 13h 19m 43.99s , +11d  4m 00.12s, R=34.9) errorbox  9 sec after notice time and 40 sec after trigger time at 2019-07-26 17:54:23 UT, with upper limit up to  19.5 mag. The observations began at zenit distance = 57 deg. The sun  altitude  is -24.4 deg. 

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


Real time updated cover map and OT discovered available here:
