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 GRB230203.27 (trigger No 697098930,07h 01m 36.00s , +73d 55m 12.0s, R=20.4) errorbox  18866 sec after notice time and 18902 sec after trigger time at 2023-02-03 11:50:27 UT, with upper limit up to  17.2 mag. The observations began at zenith distance =  4 deg. The sun  altitude  is -32.7 deg. 

The galactic latitude b = 27 deg., longitude l = 141 deg.


Real time updated cover map and OT discovered available here:
