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 GRB190608.01 (trigger No 581645543, 15h  2m 57.60s , -31d 25m 12.00s, R=2.21) errorbox  208 sec after trigger time at 2019-06-08 00:15:46 UT, with upper limit up to  19.7 mag. The observations began at zenit distance = 46 deg. The sun  altitude  is -66.4 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190608.01 errorbox  215 sec after trigger time at 2019-06-08 00:15:53 UT, with upper limit up to  19.1 mag. The observations began at zenit distance = 30 deg. The sun  altitude  is -32.7 deg. 

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