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 GRB240820.71 (trigger No 745866488,14h 28m 28.08s , +09d 51m 00.0s, R=32.13) errorbox  1802 sec after notice time and 1838 sec after trigger time at 2024-08-20 17:38:41 UT, with upper limit up to  17.9 mag. Observations started at twilight.  The observations began at zenith distance = 51 deg. The sun  altitude  is -10.7 deg. 

The galactic latitude b = 61 deg., longitude l =  1 deg.
