COMMENT: IPS HF Communications Warning 36 was issued on 28 November
and is current for interval 28-30 November. Very low solar activity
has been a key factor of the depressed conditions and generally
low ionospheric support observed over the last few days. Variable
and sometimes sustained depressed periods expected for
Equatorial/Northern AUS and Southern AUS/NZ regions for the next
3 days. Depressed MUFs and isolated disturbed periods for Antarctic
regions over this forecast period.
