COMMENT: On UT day 11 December, there were minor to moderate 
MUF depressions across the Australian region as compared to the 
monthly predicted levels. Sporadic E layers were seen across 
the Australian region and in Antarctica. Similar conditions are 
expected for UT days, 12-14 December, as a consequence of the 
continued very low levels of ionising radiation from the Sun.
