COMMENT: IPS SWF HF Communications Warning 14 was issued on 23 
May and is current for 23-24 May. Mostly normal conditions were 
observed during 22 May, with enhanced MUFs observed for Northern 
AUS and Southern AUS/NZ regions during local day. Mostly normal 
conditions are expected for 24 May with degraded conditions expected 
25May and 26May as the result of anticipated increased geomagnetic 
activity. SWFs possible over the next few days. Significantly 
degraded conditions are expected at high latitudes due to a PCA 
event likely to remain in progress for the next 2 days.
