MAXI GRB210501.83: 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) started inspect of the MAXI GRB210501.83 (trigger No 335675984,18h 03m 41.52s , -29d 48m 14.4s, R=1) errorbox 113 sec after notice time and 12664 sec after trigger time at 2021-05-01 23:21:29 UT, with upper limit up to 15.9 mag. The observations began at zenith distance = 75 deg. The sun altitude is -24.1 deg. The galactic latitude b = -4 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=1605264 We obtain a following upper limits.
