Fermi GRB 200906A: Global MASTER-Net observations report
Abstract
MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 200906A ( Fermi GBM team, GCN 28370) errorbox 1 days 28040 sec after notice time and 1 days 28073 sec after trigger time at 2020-09-07 20:59:46 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 41 deg. The sun altitude is -39.4 deg. The galactic latitude b = 30 deg., longitude l = 99 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1434684 We obtain a following upper limits.
