Sergienko (Blagoveschensk Educational State University) 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 GRB190619.02 (trigger No 582596766, 23h 17m 14.40s , +12d 51m 36.00s, R=2.05) errorbox 579 sec after trigger time at 2019-06-19 00:35:40 UT, with upper limit up to 19.0 mag. Observations started at twilight. The observations began at zenit distance = 46 deg. The sun altitude is -12.0 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB190619.02 errorbox 581 sec after trigger time at 2019-06-19 00:35:42 UT, with upper limit up to 18.4 mag. The observations began at zenit distance = 68 deg. The sun altitude is -63.1 deg. MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB190619.02 errorbox 584 sec after trigger time at 2019-06-19 00:35:45 UT, with upper limit up to 15.7 mag. The observations began at zenit distance = 83 deg. The sun altitude is -38.1 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=1054197 We obtain a following upper limits.
