COMMENT: SWS HF Communications Warning 33 was issued on 31 December
and is current for 1-2 Jan. On 1 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. Similar levels of ionospheric support
are expected for the next 3 UT days, 2-4 January, due to continued
very low levels of ionising radiation from the Sun.
