Sporadic Es were observed at several Australian sites. MUFs in 
the Australian region are expected to be mostly near predicted 
monthly levels on 13-15 January. Mild to moderate depressions 
are possible on 13 January as a consequence of the recent increase 
in geomagnetic activity. Sporadic E occurrences are expected 
to continue.
