- Аннотация: MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 220518B ( Fermi GBM team, GCN 32064) errorbox 20073 sec after notice time and 20113 sec after trigger time at 2022-05-18 22:47:05 UT, with upper limit up to 15.9 mag. Observations started at twilight. The observations began at zenith distance = 78 deg. The sun altitude is -13.2 deg. The galactic latitude b = -29 deg., longitude l = 330 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1977596 We obtain a following upper limits.
