Gabovich (Blagoveschensk Educational State University) 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 GRB 241101A ( T. M. Parsotan et al., GCN 38025) errorbox 66958 sec after notice time and 66984 sec after trigger time at 2024-11-02 00:18:10 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 87 deg. The sun altitude is -38.2 deg. The galactic latitude b = 79 deg., longitude l = 40 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2655501 We obtain a following upper limits.
