MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB190626.53 (trigger No 583245413, 12h 32m 09.60s , +38d 50m 24.00s, R=25.47) errorbox  20011 sec after trigger time at 2019-06-26 18:10:20 UT, with upper limit up to  18.2 mag. Observations started at twilight.  The observations began at zenit distance = 31 deg. The sun  altitude  is -11.4 deg. 

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