COMMENT: The ionosphere again showed some large depressions in 
the N.Aus/PNG regions, up to 30% overnight and 20% during the 
day. Depressions were also evident during the day at some mid-latitude 
and Southern Australian stations, while the NZ,subAntarctic and 
Antarctic regions were mostly normal. The expected increase in 
geomagnetic activity over the next 24-48 hours is expected to 
cause further ionospheric depressions 15-16 Jan, particularly 
in the high latitude regions.
