Fermi GRB 220523B: Global MASTER-Net observations report
Abstract
MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) started inspect of the Fermi GRB 220523B ( Fermi GBM team, GCN 32098) errorbox 24684 sec after notice time and 49281 sec after trigger time at 2022-05-24 03:05:29 UT, with upper limit up to 18.6 mag. Observations started at twilight. The observations began at zenith distance = 55 deg. The sun altitude is -10.8 deg. The galactic latitude b = 24 deg., longitude l = 157 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1982098 We obtain a following upper limits.
