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 GRB190630.26 (trigger No 583567803, 20h 27m 55.20s , - 1d 19m 48.00s, R=7.65) errorbox  1850 sec after trigger time at 2019-06-30 06:40:48 UT, with upper limit up to  18.4 mag. The observations began at zenit distance = 30 deg. The sun  altitude  is -61.8 deg. 

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