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 GRB 241207A ( Fermi GBM team, GCN 38454) errorbox 21312 sec after notice time and 21345 sec after trigger time at 2024-12-07 14:49:56 UT, with upper limit up to 13.8 mag. Observations started at twilight. The observations began at zenith distance = 40 deg. The sun altitude is -13.1 deg.
The galactic latitude b = 15 deg., longitude l = 74 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2699110
We obtain a following upper limits.
