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 GRB240414.10 (trigger No 734754044,12h 54m 02.40s , +57d 51m 36.0s, R=3.96) errorbox  48782 sec after notice time and 53922 sec after trigger time at 2024-04-14 17:19:21 UT, with upper limit up to  19.3 mag. Observations started at twilight.  The observations began at zenith distance = 32 deg. The sun  altitude  is -10.0 deg. 

The galactic latitude b = 60 deg., longitude l = 122 deg.
