COMMENT: SWS HF Communications Warning 1 was issued on 2 January
and is current for 3 Jan only. Mild MUF depressions across the
Australian region as compared to the monthly predicted levels
were observed during 2 January. 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, 3-5 January, due to continued very low levels of ionising
radiation from the Sun.
