Fermi GRB 230310A: Global MASTER-Net observations report
Abstract
MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 230310A ( Fermi GBM team, GCN 33445) errorbox 187 sec after notice time and 218 sec after trigger time at 2023-03-10 00:48:39 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 54 deg. The sun altitude is -43.8 deg. The galactic latitude b = 9 deg., longitude l = 1 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2203155 We obtain a following upper limits.
