COMMENT: IPS HF Communications Warning 45 was issued on 8 November 
and is current for interval 8-10 November (SWFs) . Depressed 
HF conditions forecast for the next 24-36hrs due to the arrival 
of shock fronts from recent CME activity on 03/04Nov resulting 
in Major Geomagnetic Storm levels. A proton event is also currently 
in progress and will affect transpolar communications. Depressed 
conditions expected for all Aus/NZ regions.
