COMMENT: IPS HF Communications Warning 51 was issued on 11 September
and is current for 11-13 Sep. Mild to significant MUF depressions
and degradations in HF conditions observed over the last 24 hours
in AUS/NZ regions due to very low levels of ionising radiation
and increased geomagnetic activity. Nearly similar HF conditions
may be expected from 13 to 15 September due to expected continued
enhancements in geomagnetic activity levels and very low levels
of ionising radiation during this period.
