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) was pointed to the Swift GRB 200608A ( M. J. Moss et al., GCN 27906) errorbox  7027 sec after notice time and 7103 sec after trigger time at 2020-06-08 19:27:01 UT, with upper limit up to  18.0 mag. The observations began at zenith distance = 82 deg. The sun  altitude  is -47.0 deg. 

The galactic latitude b = -36 deg., longitude l = 13 deg.


Real time updated cover map and OT discovered available here:

   17386 |         MASTER-SAAO |   C |   180 | 18.0 |        
Filter C is a clear (unfiltred) band. 


The observation and reduction will continue.
