MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 240328B ( Fermi GBM team, GCN 35987) errorbox 77794 sec after notice time and 77830 sec after trigger time at 2024-03-29 16:46:21 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 77 deg. The sun altitude is -35.1 deg.
The galactic latitude b = 34 deg., longitude l = 339 deg.
Real time updated cover map and OT discovered available here:
