- Аннотация: MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the Swift GRB 221027B ( A. Y. Lien et al., GCN 32867) errorbox 21757 sec after notice time and 22094 sec after trigger time at 2022-10-28 01:21:53 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 79 deg. The sun altitude is -31.2 deg. The galactic latitude b = 57 deg., longitude l = 80 deg.
