COMMENT: IPS HF Communications Warning 76 was issued on 8 November 
and is current for interval 10-13 November. Degraded HF conditions 
possible 11-12 Nov. Significantly high proton flux levels have 
been observed following a recent M7-flare which have led to high 
levels of absorption in the polar cap regions. The PCA event 
is still in progress and in expected to persist for the next 
couple of days.
