COMMENT: IPS HF Communications Warning 42 was issued on 24 August 
and is current for interval 25-28 August (SWFs) . MUFs have not 
become depressed after local dawn this morning following geomagnetic 
impulse from recent mass ejection. If geomagnetic activity increases 
during local night hours tonight, then there is a chance for 
depressed MUFs for southern region only tomorrow morning.
