Fermi trigger No 622618714: Global MASTER-Net observations report
Abstract
MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB200924.24 (trigger No 622618714,21h 19m 40.80s , +08d 42m 36.0s, R=4.88) errorbox 8518 sec after notice time and 23051 sec after trigger time at 2020-09-24 12:02:40 UT, with upper limit up to 17.5 mag. Observations started at twilight. The observations began at zenith distance = 50 deg. The sun altitude is -10.5 deg. The galactic latitude b = -28 deg., longitude l = 61 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1448090 We obtain a following upper limits.
