MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB 240710A ( Fermi GBM team, GCN 36843) errorbox  321 sec after notice time and 356 sec after trigger time at 2024-07-10 17:17:43 UT, with upper limit up to  14.8 mag. Observations started at twilight.  The observations began at zenith distance = 55 deg. The sun  altitude  is -14.4 deg. 

The galactic latitude b =  1 deg., longitude l = 41 deg.


Real time updated cover map and OT discovered available here:
