COMMENT: SWS HF Communications Warning 61 was issued on 19 November
and is current for 22 Nov only. Slight MUF depressions were observed
in the Aus/NZ regions for the UT day, 21 November. Current depressions
are most likely associated with low levels of ionising radiation.
Minor to Moderate MUF depressions are expected for the next three
days due to an increase in geomagnetic activity and low levels
of ionising radiation. Note there were isolated periods of sporadic
E observed in the Australian region mainly between 06-09UT.
