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 240501A ( Fermi GBM team, GCN 36359) errorbox 36531 sec after notice time and 36564 sec after trigger time at 2024-05-01 21:03:58 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 78 deg. The sun altitude is -63.3 deg.
The galactic latitude b = 33 deg., longitude l = 48 deg.
Real time updated cover map and OT discovered available here:
