MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB190620.91 (trigger No 582759998, 11h 19m 55.99s , -51d 49m 59.88s, R=26.75) errorbox  176 sec after trigger time at 2019-06-20 21:49:29 UT, with upper limit up to  19.0 mag. The observations began at zenit distance = 91 deg. The sun  altitude  is -20.3 deg. 

MASTER-SAAO robotic telescope  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB190620.91 errorbox  212 sec after trigger time at 2019-06-20 21:50:05 UT, with upper limit up to  18.7 mag. The observations began at zenit distance = 63 deg. The sun  altitude  is -76.0 deg. 

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