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 240407A ( Fermi GBM team, GCN 36044) errorbox 26 sec after notice time and 73 sec after trigger time at 2024-04-07 01:01:05 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 66 deg. The sun altitude is -18.3 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 240407A errorbox 96 sec after notice time and 144 sec after trigger time at 2024-04-07 01:02:16 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 69 deg. The sun altitude is -22.5 deg.
The galactic latitude b = -15 deg., longitude l = 109 deg.
