- 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 220620B ( Fermi GBM team, GCN 32233) errorbox 1110 sec after notice time and 1150 sec after trigger time at 2022-06-20 06:35:36 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 23 deg. The sun altitude is -62.5 deg. The galactic latitude b = -50 deg., longitude l = 355 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2011044 We obtain a following upper limits.
