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 GRB190913.15 (trigger No 590038994,17h 07m 28.800s , +55d 45m 36.00s, R=12.52) errorbox  59504 sec after trigger time at 2019-09-13 20:14:53 UT, with upper limit up to  18.3 mag. Observations started at twilight.  The observations began at zenit distance = 32 deg. The sun  altitude  is -14.8 deg. 

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