COMMENT: ASWFC SWF HF Communications Warning 87 was issued on
15 November and is current for 15-17 Nov. Maximum usable frequencies
(MUFs) on UT day 16-Nov were generally near predicted monthly
values, with enhancements of 15% in the Australian region and
enhancements of 25% at Cocos Islands during local day. Sporadic-E
was observed at most sites during local night hours. MUFs are
expected to be near predicted monthly values to mildly enhanced
over 17-18 Nov. There is a possibility of 15% depressions by
the end of 19-Nov in the southern Australian regions due to anticipated
geomagnetic activity from coronal hole high speed wind streams.
Isolated shortwave fadeouts are possible on 17-Nov.
