COMMENT: Extensive night-time spread-F observed at equatorial
and northern Australian sites indicating strong upwelling in
the equatorial ionospheric anomaly. Cocos Is also observed strong
night sporadic-E. Coronal hole is starting to take effect so
moderately enhanced geomagnetic conditions are expected to slightly
raise MUFs in the next couple of days but also raise variability.
