Gabovich (Blagoveschensk Educational State University) 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 GRB240711.66 (trigger No 742405878,15h 47m 28.08s , +35d 49m 01.2s, R=36.13) errorbox 4306 sec after notice time and 4322 sec after trigger time at 2024-07-11 17:03:16 UT, with upper limit up to 13.8 mag. Observations started at twilight. The observations began at zenith distance = 60 deg. The sun altitude is -15.4 deg. The galactic latitude b = 51 deg., longitude l = 57 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2527432 We obtain a following upper limits.
