COMMENT: SWS HF Communications Warning 2 was issued on 6 January
and is current for 6-8 Jan. On the UT day 7 January in the Australian
region MUFs were mostly near monthly predicted values or depressed
by 15%-25%. On 8-10 January moderately depressed MUFs are expected
as a result of the recent increase in the geomagnetic activity,
then the HF conditions are expected to gradually recover. HF
users are advised to use lower than the monthly predicted frequencies.
