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 GRB190726.64 (trigger No 585847498, 20h 41m 02.40s , +34d 17m 24.00s, R=1.17) errorbox  19135 sec after trigger time at 2019-07-26 20:43:48 UT, with upper limit up to  16.6 mag. Observations started at twilight.  The observations began at zenit distance = 58 deg. The sun  altitude  is -10.2 deg. 

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


Real time updated cover map and OT discovered available here:
