Fermi GRB 210324C: 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 210324C ( Fermi GBM team, GCN 29718) errorbox 2759 sec after notice time and 2786 sec after trigger time at 2021-03-24 20:46:24 UT, with upper limit up to 17.1 mag. The observations began at zenith distance = 81 deg. The sun altitude is -48.8 deg. The galactic latitude b = -63 deg., longitude l = 263 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1576010 We obtain a following upper limits.
