COMMENT: For 24 March HF conditions were mostly near predicted 
values with minor depressions observed at low and polar latitudes. 
Expect mostly near predicted MUFs today, 25-26 March, with isolated 
periods of Minor to Moderate depressed MUFs due to expected weak 
ionospheric storming associated with an increase in geomagnetic 
activity. Isolated cases of Sporadic E observed at Brisbane, 
Learmonth and Norfolk Island stations.
