COMMENT: SWS HF Communications Warning 47 was issued on 22 October
and is current for 23-24 Oct. Mainly due to low levels of ionising
radiation, minor to moderate MUF depressions were observed in
the Aus/NZ regions today (UT day 22 October). Minor to significant
MUF depressions may be expected in this region on 23, 24 and
25 October due to very low levels of ionising radiation and expected
rise in geomagnetic activity levels on these days.
