MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB190612.26 (trigger No 582012834,  1h 10m 16.01s , +14d  0m 00.00s, R=31.0667) errorbox  64214 sec after trigger time at 2019-06-13 00:04:04 UT, with upper limit up to  19.4 mag. Observations started at twilight.  The observations began at zenit distance = 74 deg. The sun  altitude  is -15.4 deg. 

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