COMMENT: A solar region became flare active over the past 24 hours.
Mostly normal to good HF conditions are now expected 
for today, as coronal hole induced overnight geomagnetic activity 
was less than expected.A solar coronal mass ejection is expected 
to cause degraded conditions late 02-03 Nov for southern Aus/NZ 
region only. Further shortwave fadesouts are likely today.
