COMMENT: IPS HF Communications Warning 61 was issued on 24 October
and is current for interval 25 October only. Depressions in MUFs
have been observed in southern Australian regions this morning.
This is due to an earlier than expected rise in the geomagnetic
activity due to a coronal hole. Depressions in MUFs and degradations
in HF conditions may be observed in Southern Australian regions
during the next 2 days. HF conditions in northern Australian
regions are not expected to have any significant effect of this
rise in the geo-magnetic activity.
