COMMENT: Ionospheric support/MUFs were near predicted monthly 
values over the UT day at all latitudes. Some degraded HF conditions 
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 
next three days.
