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 GRB 241115B ( Fermi GBM team, GCN 38241) errorbox 5337 sec after notice time and 5370 sec after trigger time at 2024-11-15 19:36:56 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 77 deg. The sun altitude is -25.5 deg.
The galactic latitude b = -15 deg., longitude l = 137 deg.
Real time updated cover map and OT discovered available here:
