COMMENT: On UT day 23 February, MUFs were mostly near monthly
predicted levels over most of the Australian region. The Cocos
Island region experienced mild to moderate enhancements during
both the local day and local night. The Northern Australian region
experienced mild depressions during the local day and enhancements
during the local night. Some periods of sporadic E layers were
seen across the region. During the next three UT days, 24-26
February, MUFs are expected to be mostly near monthly predicted
levels. However, mild to moderate depressions are possible due
to continued very low levels of ionising radiation from the Sun.
