expected for the next UT day, 22 March, with a chance of MUF
depressions for Northern and Southern Australian regions. On
23-24 March the HF propagation conditions are expected to be
degraded 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.
