Аннотация:ASTER-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 GRB190418.92 ( 17h 52m 12.00s , +23d 9m 00.00s, R=34.55) errorbox 11220 sec after trigger time at 2019-04-19 01:11:03 UT, with upper limit up to 17.4 mag. The observations began at zenit distance = 22 deg. The sun altitude is -17.5 deg. The galactic latitude b = -60 deg., longitude l = 98 deg.Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=999774We obtain a following upper limits.
