MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the Swift GRB 200528A ( E. Ambrosi et al., GCN 27832) errorbox 9786 sec after notice time and 9804 sec after trigger time at 2020-05-28 13:10:47 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 22 deg. The sun altitude is -12.3 deg.
The galactic latitude b = 57 deg., longitude l = 138 deg.
Real time updated cover map and OT discovered available here:

9894 | MASTER-Amur | C | 180 | 16.7 |
Filter C is a clear (unfiltred) band.
The observation and reduction will continue.
