COMMENT: On 4 January, MUFs varied mostly between near predicted
monthly levels and moderately depressed ones. Strong Sporadic
E layers were seen across the Australian region and in Antarctica.
Near predicted monthly MUFs are expected for the next UT day,
5 January. Depressions are likely on 6-7 January due to the increase
in geomagnetic activity and continued very low levels of ionising
radiation from the Sun.
