COMMENT: Mostly normal to enhanced HF conditions observed Equatorial/Aus
regions. Expect periods of degradation S Aus/NZ/Antarctic regions
on day one due to geomagnetic activity associated with an observed
minor solar wind shock. The proton event following recent flare
activity ended at 1105UT. Minor daytime absorption is expected
to continue in polar cap on day one. Possible further disturbance
in Antarctic regions on day three due to an anticipated mild
solar wind shock. Isolated radio fadeouts possible during local
day over the next week due to active sunspot region.
