MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB230116.58 (trigger No 695569700,20h 14m 24.00s , +76d 00m 00.0s, R=1.41) errorbox  85989 sec after notice time and 86001 sec after trigger time at 2023-01-17 13:41:36 UT, with upper limit up to  16.5 mag. The observations began at zenith distance = 53 deg. The sun  altitude  is -52.5 deg. 

The galactic latitude b = 22 deg., longitude l = 109 deg.
