COMMENT: IPS SWF HF Communications Warning 41 was issued on 8
November and is current for 8-9 Nov. Depressed MUF's for Southern
AUS/NZ regions observed during local day for 08Nov due to prior
overnight geomagnetic activity. Enhanced conditions for Northern
AUS and Equatorial regions and good ionospheric support for Antarctic
regions with occasional disturbed periods between 00UT-08UT.
Return to enhanced ionospheric conditions for Northern AUS/Equatorial
and Southern AUS/NZ regions for the next 2 days due to high solar
activity and associated strong ionising EUV flux (f10.7cm) levels.
Chance of MUF depressions of ~15% for Southern AUS/NZ and Antarctic
regions for 11Nov due to possible increased geomagnetic activity.
Continued chance of SWFs from current active solar regions.
