COMMENT: IPS HF Communications Warning 83 was issued on 7 November 
and is current for interval 11-13 November. Ionosphere had a 
positive response to recent glancing blow from west limb mass 
ejection. Normal HF conditions expected next two days. Moderately 
depressed/degraded conditions expected for southern Aus/NZ after 
10 Nov due to anticipated activity from a solar coronal hole. 
Northern Aus region MUFs expected to remain near normal.
