- 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 220724A ( Fermi GBM team, GCN 32423) errorbox 16981 sec after notice time and 17018 sec after trigger time at 2022-07-25 04:26:41 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 58 deg. The sun altitude is -78.3 deg. The galactic latitude b = 28 deg., longitude l = 352 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2040301 We obtain a following upper limits.
