COMMENT: IPS HF Communications Warning 8 was issued on 21 January 
and is current for interval 21-23 January. Persistent and intense 
sporadic-E observed at times at high latitudes. Increased absorption 
observed S. Ocean/Antarctic regions. Significant depressions 
are expected at times on 23 January as the result of elevated 
geomagnetic activity levels. Current geomagnetic activity is 
a consequence of recent solar flare activity. Another shock arrival 
is possible after Jan 23, due to recent solar filament erutions.
