COMMENT: Ionospheric conditions were slightly depressed across 
all Australian, Australasian Pacific and New Zealand regions, 
especially during local night time hours. Cases of strong sporadic 
E were observed in Southern Australian regions throughout the 
UT day, degrading communications. Expect ionospheric support 
to be slightly depressed over the next few days due to geomagnetic 
activity.
