- 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 220426B ( Fermi GBM team, GCN 31951) errorbox 57 sec after notice time and 86 sec after trigger time at 2022-04-26 07:12:02 UT, with upper limit up to 17.6 mag. The observations began at zenith distance = 85 deg. The sun altitude is -45.5 deg. The galactic latitude b = 24 deg., longitude l = 244 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1954626 We obtain a following upper limits.
