COMMENT: SWS HF Communications Warning 34 was issued on 26 July
and is current for 26-27 Jul. Variable ionospheric support for
Northern AUS and Equatorial regions over the last 24 hours with
brief periods of enhancement and notable depressed MUF's. Similar
conditions for Southern AUS and NZ regions with disturbed conditions
for Antarctic regions. Only minor ionospheric recovery is to
be expected over the next 24 hours due to low solar activity
and anticipated arrival of further coronal hole driven geomagnetic
activity over the next 3 days resulting in depressed MUF's of
~~20% for 28-29Jul.
