COMMENT: SWS HF Communications Warning 27 was issued on 15 May 
and is current for 16-18 May. Minor to mild MUF depressions were 
observed in the northern and central parts of Aus regions today 
(16 May). Minor to mild MUF enhancements were observed in the 
Southern Aus regions on this day. Minor to moderate MUF depressions 
and degradations in HF conditions may be expected in this region 
from 17 to 18 May due to expected continued rise in geomagnetic 
activity levels on these days. MUFs and HF conditions are expected 
to gradually recover to mostly normal levels in this region on 
19 May.
