COMMENT: Frequencies of ionospheric support in the Australian 
region were briefly depressed after local dawn yesterday at some 
southern Australian region sites and then recovered. Strong enhancements 
were observed at lower latitude sites. With little induced geomagnetic 
activity overnight, frequencies are now expected to be near predicted 
monthly values to 15% enhanced. Degraded HF conditions are possible 
during local night hours for southern region Australia over the 
next few days.
