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 201221E ( Fermi GBM team, GCN 29114) errorbox 19065 sec after notice time and 20298 sec after trigger time at 2020-12-22 05:07:05 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 49 deg. The sun altitude is -35.0 deg.
The galactic latitude b = 16 deg., longitude l = 276 deg.
