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 240607A ( Fermi GBM team, GCN 36634) errorbox 46211 sec after notice time and 46269 sec after trigger time at 2024-06-07 23:52:24 UT, with upper limit up to 19.8 mag. The observations began at zenith distance = 82 deg. The sun altitude is -71.1 deg.
The galactic latitude b = -83 deg., longitude l = 258 deg.
Real time updated cover map and OT discovered available here:
