COMMENT: On UT day 31 January, MUFs were slightly depressed to
near monthly predicted levels over most Australian region. Northern
Australian region and the Niue Island region had Moderate MUF
depressions during the local day. Sporadic E layers were over
some Australian ionosonde stations. Slightly stronger depressions
may be observed on UT days 01-02 February as a consequence of
very low levels of ionising radiation from the Sun and increased
geomagnetic activity associated with coronal hole effects.
