Date   T index  Conditions       MUFs

COMMENT: Mostly near predicted monthly MUFs were observed for 
Australian region on UT day 24 March. Similar to slightly improved 
MUF conditions are expected on UT day 25 March, due the onset 
of disturbed geomagnetic conditions associated with 20 March 
CME. On 26 March, the HF propagation conditions are expected 
to degrade as the aftermath of the expected active geomagnetic 
conditions.
