Integral GRB221218.34: 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 Integral GRB221218.34 (trigger No 141204,23h 22m 36.00s , -04d 15m 38.5s, R=0.0436) errorbox 22820 sec after notice time and 22925 sec after trigger time at 2022-12-18 14:37:57 UT, with upper limit up to 18.5 mag. Observations started at twilight. The observations began at zenith distance = 47 deg. The sun altitude is -10.7 deg. The galactic latitude b = -59 deg., longitude l = 77 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2185335 We obtain a following upper limits.
