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 GRB190422.67 ( 12h 36m 55.20s , -54d 57m 00.00s, R=7.96) errorbox  22200 sec after trigger time at 2019-04-22 22:15:04 UT, with upper limit up to  17.1 mag. The observations began at zenit distance = 85 deg. The sun  altitude  is -33.1 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190422.67 errorbox  24752 sec after trigger time at 2019-04-22 22:57:37 UT, with upper limit up to  17.6 mag. Observations started at twilight.  The observations began at zenit distance = 50 deg. The sun  altitude  is -11.4 deg. 

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