COMMENT: HF frequency conditions were averaging near Normal for 
mid-latitudes with less fluctuations than the previous two days 
as the ongoing geomagnetic activity from a high-speed solar wind 
stream from large coronal hole (CH520), began to wane. Strong 
overnight spread-F at low-latitudes as the 3rd day of geomagnetic 
activity took effect on the inner magnetosphere, connected to the 
low latitude ionosphere. Wind speed had declined to ~650km/s by 
22UT and will decline further on 7 June.
