COMMENT: Due to very low levels of ionising radiation from the 
Sun, MUF depressions of 15 to 30% were observed across the Australian 
region on UT day 2 December. Similar and even slightly higher 
levels of MUF depressions in the Australian region may be expected 
on UT day 3 December due to expected rise in geomagnetic activity 
levels on this day and due to the continued very low levels of 
ionising radiation from the Sun. Minor to moderate MUF depressions 
in this region are also likely to continue on UT days 4 and possibly 
5 December.
