Warning 9 was issued on 14 February and is current for 15-16
Feb. The ionosphere in the Australian region was mostly normal
to enhanced over the last 24 hours. MUFs were generally above
predicted monthly values at most locations. MUFs are expected
to continue to be enhanced 15-Feb, however an expected increase
in geomagnetic activity may result in degraded HF conditions
15-Feb and some MUF depressions to 30% on 16-Feb, particularly
at S.Aus/NZ/Antarctic locations. Further short-wave fadeouts
are likely over the next 2 days.
