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 240629A ( Fermi GBM team, GCN 36786) errorbox 3278 sec after notice time and 3311 sec after trigger time at 2024-06-29 17:49:04 UT, with upper limit up to 15.4 mag. The observations began at zenith distance = 80 deg. The sun altitude is -25.7 deg.
The galactic latitude b = -41 deg., longitude l = 4 deg.
Real time updated cover map and OT discovered available here:
