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 GRB240801.48 (trigger No 744204856,08h 38m 07.92s , +19d 25m 01.2s, R=35.17) errorbox 23511 sec after notice time and 23543 sec after trigger time at 2024-08-01 18:06:35 UT, with upper limit up to 13.9 mag. Observations started at twilight. The observations began at zenith distance = 70 deg. The sun altitude is -10.0 deg.
The galactic latitude b = 32 deg., longitude l = 206 deg.
Real time updated cover map and OT discovered available here:
