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) started inspect of the Fermi GRB231230.06 (trigger No 725592555,16h 02m 48.00s , +53d 33m 36.0s, R=5.2) errorbox 27 sec after notice time and 67 sec after trigger time at 2023-12-30 01:30:17 UT, with upper limit up to 18.8 mag. The observations began at zenith distance = 54 deg. The sun altitude is -39.8 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB231230.06 errorbox 31 sec after notice time and 70 sec after trigger time at 2023-12-30 01:30:20 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 51 deg. The sun altitude is -34.0 deg.
The galactic latitude b = 46 deg., longitude l = 83 deg.
