COMMENT: Mostly near predicted monthly MUFs were observed for
Australian region on UT day 23 March, with mild depressions for
Northern Australian region during local day. Similar to slightly
improved MUF conditions are expected on UT day 24 March, due
the expected onset of disturbed geomagnetic conditions associated
with 20 March CME. On 25 March the HF propagation conditions
are expected to degrade due to the predicted increase in the
geomagnetic activity up to Storm levels.
