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) was pointed to the Swift GRB241026.95 (trigger No 1262764,19h 33m 41.52s , +57d 58m 48.0s, R=0.05) errorbox 10 sec after notice time and 40 sec after trigger time at 2024-10-26 22:43:12 UT, with upper limit up to 16.7 mag. The observations began at zenith distance = 69 deg. The sun altitude is -51.7 deg.
The galactic latitude b = 17 deg., longitude l = 90 deg.
