COMMENT: Observed MUF's for the Australasia regions on the UT 
day 08 Nov were strongly degraded. This degradation is due to 
negative storm effects in ionosphere following the passage of 
the CME. The two day outlook is for HF conditions to remain degraded. 
The onset of high speed solar streams from the approaching very 
large recurrent positive northern coronal will further delay 
the recovery of MUFs.
