MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB190804.36 (trigger No 586600841,  3h 24m 16.01s , +42d 34m 59.88s, R=33.2167) errorbox  39067 sec after trigger time at 2019-08-04 19:31:43 UT, with upper limit up to  17.0 mag. The observations began at zenit distance = 79 deg. The sun  altitude  is -21.2 deg. 

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


Real time updated cover map and OT discovered available here:
