COMMENT: Minor to significant MUF depressions were observed across
Aus/NZ region today due to enhanced geomagnetic activity levels.
Some periods of MUF enhancements were also observed. Minor to
mild degradations in HF conditions and MUF depressions may be
expected for this region for the next two days as the geomagnetic
activity is expected to stay relatively higher for two more days.
Mostly normal HF conditions may be expected for the third day
as the geomagnetic activity is expected to show significant decline
by then.
