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 GRB190606.08 (trigger No 581478912, 23h 59m 43.92s , +57d 57m 00.00s, R=3.28) errorbox  83 sec after trigger time at 2019-06-06 01:56:30 UT, with upper limit up to  17.7 mag. The observations began at zenit distance = 68 deg. The sun  altitude  is -37.7 deg. 

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