COMMENT: Mild degradation in HF conditions overnight, due to 
transit of weak coronal mass ejection. Brief mild depressions 
of 10-15% may be experienced this morning at some southern Aus/NZ 
region sites. MUFs are generally expected to be near predicted 
monthly values, however there is a chance for further mildly 
degraded conditions today, during local night hours, due to possible 
arrival of another weak mass ejection.
