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 231028A ( M. A. Williams et al., GCN 34894) errorbox 39827 sec after notice time and 39846 sec after trigger time at 2023-10-28 15:13:16 UT, with upper limit up to 14.5 mag. Observations started at twilight. The observations began at zenith distance = 78 deg. The sun altitude is -12.3 deg.
MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the Swift GRB 231028A errorbox 65649 sec after notice time and 65669 sec after trigger time at 2023-10-28 22:23:38 UT, with upper limit up to 16.0 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -14.4 deg.
The galactic latitude b = 69 deg., longitude l = 20 deg.
