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 GRB240512.10 (trigger No 737173236,11h 08m 40.08s , -43d 19m 01.2s, R=4.88) errorbox  98 sec after notice time and 132 sec after trigger time at 2024-05-12 02:22:43 UT, with upper limit up to  17.2 mag. The observations began at zenith distance = 85 deg. The sun  altitude  is -37.2 deg. 

The galactic latitude b = 16 deg., longitude l = 284 deg.


Real time updated cover map and OT discovered available here:
