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) was pointed to the Swift GRB 240805A ( S. Dichiara et al., GCN 37032) errorbox 53063 sec after notice time and 53081 sec after trigger time at 2024-08-05 16:47:04 UT, with upper limit up to 16.1 mag. Observations started at twilight. The observations began at zenith distance = 33 deg. The sun altitude is -9.3 deg.
The galactic latitude b = 9 deg., longitude l = 302 deg.
Real time updated cover map and OT discovered available here:
