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 GRB190805.24 (trigger No 586676451, 14h 35m 24.00s , -38d 10m 01.20s, R=50) errorbox  54248 sec after trigger time at 2019-08-05 20:44:54 UT, with upper limit up to  17.4 mag. Observations started at twilight.  The observations began at zenit distance = 72 deg. The sun  altitude  is -11.9 deg. 

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