- 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 220623B ( Fermi GBM team, GCN 32249) errorbox 1 days 36625 sec after notice time and 1 days 36660 sec after trigger time at 2022-06-25 01:44:57 UT, with upper limit up to 15.2 mag. The observations began at zenith distance = 79 deg. The sun altitude is -51.2 deg. The galactic latitude b = 61 deg., longitude l = 91 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2013845 We obtain a following upper limits.
