- Аннотация: 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) started inspect of the Fermi GRB 220523A ( Fermi GBM team, GCN 32092) errorbox 293 sec after notice time and 330 sec after trigger time at 2022-05-23 04:17:00 UT, with upper limit up to 13.7 mag. The observations began at zenith distance = 81 deg. The sun altitude is -23.0 deg. MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 220523A errorbox 1093 sec after notice time and 1130 sec after trigger time at 2022-05-23 04:30:20 UT, with upper limit up to 16.4 mag. The observations began at zenith distance = 82 deg. The sun altitude is -79.5 deg. The galactic latitude b = 7 deg., longitude l = 262 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1981570 We obtain a following upper limits.
