COMMENT: Depressed MUFs again observed around local dawn this 
morning for Aus/NZ region. Depression associated with geomagnetic 
activity induced by coronal hole high speed wind stream. Intense 
daytime sporadic-E observed at low to mid latitudes. Persistent 
and occasionally intense spread-F conditions observed at mid 
to high latitudes. Increased absorption observed at times Southern 
Ocean region. Extended interval of lower than normal MUFs for 
southern Aus/NZ region probable over next few days. Depressed 
MUF conditions may ease slightly after 15 Nov.
