COMMENT: SWS HF Communications Warning 14 was issued on 16 February
and is current for 17-19 Feb. MUFs were mostly near monthly predicted
levels with sporadic minor depressions scattered across the Australian
regions during UT day 18 February. Over the next two days (19-20
February), similar MUF levels are expected as the ionosphere
gradually recovers from disturbed geomagnetic conditions associated
with the coronal hole.
