Swift GRB 200922A: 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) was pointed to the Swift GRB 200922A ( M. J. Moss et al., GCN 28471) errorbox 37015 sec after notice time and 37039 sec after trigger time at 2020-09-22 22:24:05 UT, with upper limit up to 20.5 mag. The observations began at zenith distance = 48 deg. The sun altitude is -57.9 deg. The galactic latitude b = -30 deg., longitude l = 343 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1446564 We obtain a following upper limits.
