MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 231115A ( Fermi GBM team, GCN 35035) errorbox 4601 sec after notice time and 4635 sec after trigger time at 2023-11-15 16:53:37 UT, with upper limit up to 18.8 mag. The observations began at zenith distance = 47 deg. The sun altitude is -57.5 deg.
The galactic latitude b = 34 deg., longitude l = 141 deg.
Real time updated cover map and OT discovered available here:
