COMMENT: On UT day 10 February, MUFs were mostly near monthly
predicted levels to depressed by around 20% across most parts
of Australian/NZ regions. Periods of mild to moderate MUF enhancements
were also observed in some northern areas. Strong sporadic E
layers were also observed. Minor to moderate MUF depressions
and degradations in HF conditions may be observed in the Aus/NZ
regions for the next three days (UT days 11 to 13 February) due
to continued very low levels of ionising radiation from the Sun
and some possibility of slight rise in geomagnetic activity levels
on UT days 12 and 13 February.
