Fermi GRB 220222A: 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 220222A ( Fermi GBM team, GCN 31630) errorbox 697 sec after notice time and 725 sec after trigger time at 2022-02-22 02:33:23 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 65 deg. The sun altitude is -18.3 deg. The galactic latitude b = -66 deg., longitude l = 162 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1891006 We obtain a following upper limits.
