COMMENT: IPS HF Communications Warning 1 was issued on 2 January 
and is current for interval 2-4 January. MUF depressions of 20% 
observed at times across Northern AUS/Equatorial regions during 
the last 24 hours. Similar conditions for Southern AUS/NZ regions 
with notable sporadic E. Mostly normal conditions for Antarctic 
regions. Similar conditions expected for the next few days with 
a possible improvement for mid to low latitudes from increased 
solar activity. Chance of disturbed ionospheric conditions for 
polar regions due to transient effects from recent CME's.
