COMMENT: ASWFC HF Communications Warning 100 was issued on 1 
November and is current for 1-2 Nov. Maximum Usable Frequencies 
(MUFs) in the Australian region on UT day 01-Nov showed depressions 
of up to 40% due to ongoing geomagnetic activity. Depressions 
were observed throughout the entire UT day in the southern Australian 
region, and observed mostly during local day in the northern 
Australian region. Sporadic E was observed at both Canberra and 
Perth, with Spread F visible at Hobart. MUFs are forecast to 
remain depressed on 02-Nov, before trending towards predicted 
monthly values across 03-04 Nov as geomagnetic conditions ease.
