COMMENT: Occasionally strong sporadic-E and spread-F conditions 
observed at high latitudes. Expect periods of degradation S Aus/NZ 
regions next two days due to geomagnetic activity associated 
with a high speed coronal hole wind stream. Proton event following 
recent flare activity is still in progress, but expected to decline 
after today. Isolated radio fadeouts possible during local day 
over the next week due to returning active solar region.
