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 240305C ( Fermi GBM team, GCN 35881) errorbox 390 sec after notice time and 423 sec after trigger time at 2024-03-05 22:23:40 UT, with upper limit up to 13.6 mag. The observations began at zenith distance = 77 deg. The sun altitude is -50.3 deg.
The galactic latitude b = 17 deg., longitude l = 20 deg.
Real time updated cover map and OT discovered available here:
