COMMENT: Northern Aus region MUFs again expected to be near normal. 
In general southern region MUFs are expected to improve after 
today. However, an extended period of lower than normal MUFs 
after local dawn and degraded local night conditions may be experienced 
by southern Aus/NZ HF communicators. Degraded conditions expected 
again today in Antarctic regions with persistent, extensive spread-F 
conditions prevailing. Chance for shortwave fadeouts.
