- Аннотация: 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) was pointed to the Swift GRB190427.19 ( 18h 40m 51.12s , +40d 19m 19.20s, R=0.05) errorbox 40 sec after trigger time at 2019-04-27 04:34:54 UT, with upper limit up to 18.6 mag. The observations began at zenit distance = 16 deg. The sun altitude is -23.5 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) was pointed to the Swift GRB190427.19 errorbox 44 sec after trigger time at 2019-04-27 04:34:58 UT, with upper limit up to 13.2 mag. Observations started at twilight. The observations began at zenit distance = 75 deg. The sun altitude is -7.5 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=1004408 We obtain a following upper limits.
