MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 231030B ( Fermi GBM team, GCN 34915) errorbox 118 sec after trigger time at 2023-10-30 20:00:18 UT, with upper limit up to 15.5 mag. The observations began at zenith distance = 70 deg. The sun altitude is -36.7 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 231030B errorbox 53 sec after notice time and 175 sec after trigger time at 2023-10-30 20:01:15 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 71 deg. The sun altitude is -54.7 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 231030B errorbox 446 sec after notice time and 567 sec after trigger time at 2023-10-30 20:07:47 UT, with upper limit up to 15.8 mag. The observations began at zenith distance = 74 deg. The sun altitude is -59.1 deg.
The galactic latitude b = 43 deg., longitude l = 86 deg.
