MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB 240828A ( Fermi GBM team, GCN 37317) errorbox 140 sec after notice time and 176 sec after trigger time at 2024-08-28 14:58:02 UT, with upper limit up to 15.9 mag. The observations began at zenith distance = 74 deg. The sun altitude is -30.0 deg.
The galactic latitude b = 66 deg., longitude l = 60 deg.
Real time updated cover map and OT discovered available here:
