were experienced at high and mid latitude sites as a result of
increased geomagnetic activity. Considerable periods of sporadic-E
were again observed at mid-latitude sites in the afternoon and
around dusk, as well as near sunrise on the east coast of Australia.
Expect some mildly degraded HF conditions in the S.Aus/Antarctic
regions 22 Nov. MUFs near predicted monthly values but decreasing
