COMMENT: Variable night-time depressions observed Equatorial/N 
Aus regions. Widespread and persistent sporadic-E observed S 
Aus/Antarctic regions mainly local morning/evening, with occasional 
slant sporadic-E in the polar cap. Daytime spread-F at high latitudes. 
Increased ionospheric activity due to a high speed coronal hole 
wind stream should see a reduction in low-latitude variability, 
and further periods of disturbance at higher latitudes next two 
to three days.
