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 GRB190723.31 (trigger No 585559462, 19h 17m 52.80s , +25d 13m 12.00s, R=10.47) errorbox  47818 sec after trigger time at 2019-07-23 20:41:15 UT, with upper limit up to  19.4 mag. The observations began at zenit distance = 10 deg. The sun  altitude  is -24.1 deg. 

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


Real time updated cover map and OT discovered available here:
