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 GRB241004.00 (trigger No 749693019,09h 03m 52.08s , -62d 37m 01.2s, R=50) errorbox 15 sec after notice time and 48 sec after trigger time at 2024-10-04 00:04:22 UT, with upper limit up to 19.0 mag. The observations began at zenith distance = 48 deg. The sun altitude is -47.0 deg.
The galactic latitude b = -10 deg., longitude l = 280 deg.
Real time updated cover map and OT discovered available here:
