Fermi GRB 220627A: Global MASTER-Net observations report

MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 220627A ( Fermi GBM team, GCN 32278) errorbox 579 sec after notice time and 592 sec after trigger time at 2022-06-27 21:30:52 UT, with upper limit up to 19.9 mag. The observations began at zenith distance = 39 deg. The sun altitude is -72.1 deg. The galactic latitude b = 25 deg., longitude l = 320 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2016919 We obtain a following upper limits.
