MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB230703.95 (trigger No 710117592,21h 01m 00.00s , +47d 31m 48.0s, R=1) errorbox  74910 sec after notice time and 74941 sec after trigger time at 2023-07-04 19:42:08 UT, with upper limit up to  18.4 mag. The observations began at zenith distance = 38 deg. The sun  altitude  is -20.7 deg. 

The galactic latitude b =  1 deg., longitude l = 89 deg.
