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 240611A ( Fermi GBM team, GCN 36658) errorbox 9612 sec after notice time and 9643 sec after trigger time at 2024-06-11 13:19:42 UT, with upper limit up to 13.2 mag. Observations started at twilight. The observations began at zenith distance = 29 deg. The sun altitude is -11.4 deg.
The galactic latitude b = 30 deg., longitude l = 107 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2489453
We obtain a following upper limits.
