COMMENT: ASWFC SWF HF Communications Warning 24 was issued on 
1 March and is current for 1-3 Mar. Maximum usable frequencies 
(MUFs) in the Australian region were mostly 20-30% enhanced. 
Sporadic-E was observed at Brisbane during local night and spread-F 
was observed in Hobart during local night. MUFs are expected 
to be near 20-25% enhanced over 3-4 Mar, and near monthly predicted 
values on 5-Mar due to anticipated mild geomagnetic activity 
from a coronal hole wind stream. Shortwave fadeouts are possible.
