MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB230523.51 (trigger No 706536788,11h 48m 04.80s , -54d 19m 48.0s, R=24.36) errorbox 33885 sec after notice time and 33920 sec after trigger time at 2023-05-23 21:38:23 UT, with upper limit up to 19.5 mag. The observations began at zenith distance = 50 deg. The sun altitude is -72.9 deg.
The galactic latitude b = 7 deg., longitude l = 294 deg.
Real time updated cover map and OT discovered available here:
