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 GRB230512.27 (trigger No 705565670,18h 30m 28.80s , +53d 52m 12.0s, R=1) errorbox 1 days 20807 sec after notice time and 1 days 20838 sec after trigger time at 2023-05-13 12:15:04 UT, with upper limit up to 17.7 mag. Observations started at twilight. The observations began at zenith distance = 56 deg. The sun altitude is -9.7 deg.
The galactic latitude b = 24 deg., longitude l = 83 deg.
Real time updated cover map and OT discovered available here:
