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) was pointed to the  Fermi GRB190415.17 ( 21h 13m 31.99s , +71d 46m 59.88s, R=3.7) 61 sec after trigger time at 2019-04-15 04:10:51 UT, with upper limit up to  17.2 mag. The observations began at zenit distance = 57 deg. The sun  altitude  is -31.1 deg. 

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


Real time updated cover map and OT discovered available here:
