Fermi GRB 230313A: Global MASTER-Net observations report
Abstract
MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB 230313A ( Fermi GBM team, GCN 33467) errorbox 34 sec after notice time and 69 sec after trigger time at 2023-03-13 11:39:52 UT, with upper limit up to 15.6 mag. The observations began at zenith distance = 57 deg. The sun altitude is -21.1 deg. The galactic latitude b = 69 deg., longitude l = 104 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2204375 We obtain a following upper limits.
