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 GRB240516.15 (trigger No 737523389,13h 31m 43.99s , -65d 37m 00.1s, R=11.05) errorbox  13 sec after notice time and 48 sec after trigger time at 2024-05-16 03:37:13 UT, with upper limit up to  17.3 mag. The observations began at zenith distance = 65 deg. The sun  altitude  is -21.9 deg. 

The galactic latitude b = -3 deg., longitude l = 307 deg.


Real time updated cover map and OT discovered available here:
