COMMENT: Persistent and occasionally intense sporadic-E conditions 
observed S Aus/NZ regions during local day. General recovery 
in HF conditions observed early in the UT day at low to mid latitudes, 
but brief overnight depressions at low latitudes. High latitudes 
showed overnight recovery to near-normal conditions. Expect mostly 
normal HF conditions today at low to mid latitudes, with a possibility 
of disturbances at high latitudes due to the anticipated mild 
coronal hole wind stream. Disturbances may spread to lower latitudes 
on day two, followed by general recovery on day three.
