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 GRB230510.50 (trigger No 705413051,21h 29m 19.20s , +31d 00m 00.0s, R=2.57) errorbox 14026 sec after notice time and 14057 sec after trigger time at 2023-05-10 15:58:24 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 64 deg. The sun altitude is -22.1 deg.
The galactic latitude b = -15 deg., longitude l = 80 deg.
Real time updated cover map and OT discovered available here:
