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 GRB240311.36 (trigger No 731839490,22h 18m 24.00s , +05d 37m 58.8s, R=33.28) errorbox 38228 sec after notice time and 38263 sec after trigger time at 2024-03-11 19:22:28 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 68 deg. The sun altitude is -24.2 deg.
The galactic latitude b = -41 deg., longitude l = 69 deg.
Real time updated cover map and OT discovered available here:
