COMMENT: SWS HF Communications Warning 12 was issued on 5 November
and is current for 5-6 Nov. MUFs were depressed by 20% over Southern
Australian and Antarctic regions during UT day, 05 November,
due to minor geomagnetic storming and continued very low levels
of ionising radiation. Northern Australia was mostly near predicted
MUF values. Expect this trend to continue today, 06 November.
Due to low number of active regions on the Sun, expect the low
levels of ionising radiation to continue with possible depressions
to continue on 07-08 November.
