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 240402A ( Fermi GBM team, GCN 36012) errorbox 56 sec after notice time and 92 sec after trigger time at 2024-04-02 23:45:36 UT, with upper limit up to 19.8 mag. The observations began at zenith distance = 17 deg. The sun altitude is -30.8 deg.
MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 240402A errorbox 283 sec after notice time and 318 sec after trigger time at 2024-04-02 23:49:23 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 78 deg. The sun altitude is -59.0 deg.
The galactic latitude b = 65 deg., longitude l = 44 deg.
