MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240512.92 (trigger No 737244199,03h 37m 40.01s , +45d 45m 00.0s, R=50) errorbox 1370 sec after notice time and 1406 sec after trigger time at 2024-05-12 22:26:41 UT, with upper limit up to 18.9 mag. The observations began at zenith distance = 44 deg. The sun altitude is -26.7 deg.
The galactic latitude b = -7 deg., longitude l = 151 deg.
Real time updated cover map and OT discovered available here:
