COMMENT: Extensive night-time spread-F observed at equatorial 
and northern Australian sites indicating strong upwelling in 
the equatorial ionospheric anomaly. Coronal hole taking effect 
and slightly enhanced geomagnetic conditions seem to be raising 
MUFs across the region. Expected to continue for a day but also 
increase MUF variability.
