MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB190530.43 (trigger No 580904353,  7h 47m 40.80s , +33d 57m 00.00s, R=1) errorbox  15845 sec after trigger time at 2019-05-30 14:43:13 UT, with upper limit up to  17.0 mag. Observations started at twilight.  The observations began at zenit distance = 67 deg. The sun  altitude  is -10.9 deg. 

MASTER-IAC robotic telescope  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB190530.43 errorbox  37305 sec after trigger time at 2019-05-30 20:40:53 UT, with upper limit up to  18.6 mag. Observations started at twilight.  The observations began at zenit distance = 55 deg. The sun  altitude  is -10.0 deg. 

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