Swift GRB 220302A: 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) was pointed to the Swift GRB 220302A ( E. Troja et al., GCN 31661) errorbox 2514 sec after notice time and 2575 sec after trigger time at 2022-03-02 08:23:15 UT, with upper limit up to 16.6 mag. The observations began at zenith distance = 87 deg. The sun altitude is -63.3 deg. The galactic latitude b = 9 deg., longitude l = 84 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1899637 We obtain a following upper limits.
