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 GRB240511.86 (trigger No 737152719,10h 59m 40.08s , -79d 46m 58.8s, R=50) errorbox  831 sec after notice time and 869 sec after trigger time at 2024-05-11 20:53:04 UT, with upper limit up to  18.5 mag. The observations began at zenith distance = 81 deg. The sun  altitude  is -63.2 deg. 

The galactic latitude b = -18 deg., longitude l = 298 deg.


Real time updated cover map and OT discovered available here:
