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 GRB190515.49 (trigger No 579613314, 17h 52m 16.08s , +38d  3m 00.00s, R=34.3) errorbox  1 days 27561 sec after trigger time at 2019-05-16 19:21:10 UT, with upper limit up to  17.2 mag. The observations began at zenit distance = 105 deg. The sun  altitude  is -44.8 deg. 

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