COMMENT: IPS HF Communications Warning 43 was issued on 2 June 
and is current for interval 3-5 June. Northern Aus region MUFS 
have been near predicted monthly values and are expected to remain 
mostly unaffected by coronal hole high speed wind stream induced 
geomagnetic activity. Expect degraded conditions with associated 
geomagnetic activity at high latitudes for at least the next 
few days.
