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 GRB190626.25 (trigger No 583221986,  9h 42m 48.00s , -41d  6m 36.00s, R=6.25) errorbox  38130 sec after trigger time at 2019-06-26 16:41:51 UT, with upper limit up to  19.2 mag. Observations started at twilight.  The observations began at zenit distance = 33 deg. The sun  altitude  is -12.2 deg. 

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