- Аннотация: MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB190427.19 ( 18h 10m 04.08s , +46d 49m 58.80s, R=3.5) errorbox 45378 sec after trigger time at 2019-04-27 17:10:33 UT, with upper limit up to 19.8 mag. The observations began at zenit distance = 36 deg. The sun altitude is -25.2 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=1004400We obtain a following upper limits.
