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) started inspect of the Fermi GRB231215.41 (trigger No 724326442,00h 44m 14.40s , +61d 13m 48.0s, R=1) errorbox 22709 sec after notice time and 22743 sec after trigger time at 2023-12-15 16:06:21 UT, with upper limit up to 18.3 mag. The observations began at zenith distance = 19 deg. The sun altitude is -26.4 deg.
The galactic latitude b = -1 deg., longitude l = 122 deg.
Real time updated cover map and OT discovered available here:
