Swift GRB 221216A: Global MASTER-Net observations report
Abstract
MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB 221216A ( S. Dichiara et al., GCN 33067) errorbox 11435 sec after notice time and 11456 sec after trigger time at 2022-12-16 14:32:17 UT, with upper limit up to 15.4 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -9.8 deg. The galactic latitude b = -50 deg., longitude l = 11 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2184841 We obtain a following upper limits.
