MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190508.11 (trigger No 578975670, 13h 48m 55.92s , -71d 52m 58.80s, R=24.55) errorbox  3931 sec after trigger time at 2019-05-08 03:39:56 UT, with upper limit up to  18.9 mag. The observations began at zenit distance = 41 deg. The sun  altitude  is -71.7 deg. 

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