MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB230911.72 (trigger No 716145795,13h 20m 04.08s , +22d 45m 00.0s, R=22.5) errorbox 3923 sec after notice time and 3931 sec after trigger time at 2023-09-11 18:28:41 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 76 deg. The sun altitude is -30.4 deg.
The galactic latitude b = 82 deg., longitude l = 1 deg.
