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 GRB240814.23 (trigger No 745306088,09h 25m 52.80s , +54d 35m 24.0s, R=15.08) errorbox  48288 sec after notice time and 48323 sec after trigger time at 2024-08-14 18:53:27 UT, with upper limit up to  16.9 mag. The observations began at zenith distance = 84 deg. The sun  altitude  is -19.7 deg. 

The galactic latitude b = 44 deg., longitude l = 162 deg.


Real time updated cover map and OT discovered available here:
