COMMENT: SWS SWF HF Communications Warning 3 was issued on 22
March and is current for 22-23 Mar. Mostly near predicted monthly
MUFs were observed for Australian region on UT day 22 March,
with mild depressions for Northern Australian region during local
day. Similar conditions are expected for the beginning of the
next UT day, 23 March, with a chance of MUF depressions for Northern
and Southern Australian regions. Later on 23 March and on 24
March the HF propagation conditions are expected to degrade due
to the predicted increase in the geomagnetic activity up to Storm
levels. Mildly enhanced MUFs are expected for 23-24 March as
a consequence of the predicted geomagnetic storm.
