Fermi GRB 240328A: Global MASTER-Net observations report
Abstract
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 240328A ( Fermi GBM team, GCN 35986) errorbox 1 days 15952 sec after notice time and 1 days 15986 sec after trigger time at 2024-03-29 16:47:48 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 75 deg. The sun altitude is -35.1 deg. The galactic latitude b = 41 deg., longitude l = 0 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2409243 We obtain a following upper limits.
