Swift GRB 200917A: 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) was pointed to the Swift GRB 200917A ( E. Sonbas et al., GCN 28435) errorbox 46136 sec after notice time and 46245 sec after trigger time at 2020-09-17 16:43:13 UT, with upper limit up to 15.9 mag. Observations started at twilight. The observations began at zenith distance = 64 deg. The sun altitude is -10.4 deg. The galactic latitude b = 37 deg., longitude l = 2 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1443272 We obtain a following upper limits.
