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 220306A ( Fermi GBM team, GCN 31693) errorbox 218 sec after notice time and 247 sec after trigger time at 2022-03-06 07:24:07 UT, with upper limit up to 18.6 mag. The observations began at zenith distance = 67 deg. The sun altitude is -64.7 deg.
The galactic latitude b = 32 deg., longitude l = 295 deg.
Real time updated cover map and OT discovered available here:
