of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

Date   T index
10 Mar   128

Observed Australian Regional MUFs
Mostly near predicted monthly values to enhaced at all
stations, with depressions of up to 15% since local dawn
for southern regions.


Predicted Monthly T index for March:  82

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
11 Mar   110    Isolated depressions of 5-15% at times to enhanced
