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 220610A ( Fermi GBM team, GCN 32188) errorbox  2670 sec after notice time and 2707 sec after trigger time at 2022-06-10 22:29:44 UT, with upper limit up to  17.2 mag. Observations started at twilight.  The observations began at zenith distance = 55 deg. The sun  altitude  is -10.7 deg. 

The galactic latitude b = 62 deg., longitude l = 211 deg.
