Warning 24 was issued on 11 March and is current for 12-14 Mar. 
Maximum usable frequencies (MUFs) on 12 March were near predicted 
monthly values to about 20% enhanced at times. Spread F was observed 
overnight at Hobart. MUFs are generally expected to be near predicted 
monthly values to mildly enhanced on 13 Mar. Geomagnetic activity 
expected in the second half of 13 Mar or early 14 Mar is expected 
to degrade conditions from then. Degraded MUFs are expected into 
15 Mar, improving later.
