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 240610A ( Fermi GBM team, GCN 36651) errorbox 689 sec after notice time and 723 sec after trigger time at 2024-06-10 00:15:21 UT, with upper limit up to 18.1 mag. The observations began at zenith distance = 43 deg. The sun altitude is -66.7 deg.
The galactic latitude b = -6 deg., longitude l = 47 deg.
Real time updated cover map and OT discovered available here:
