2. FORECAST (05 APRIL - 07 APRIL)
Date   T index  Conditions       MUFs                              
05 Apr   105    Normal           Near predicted monthly values

COMMENT: Maximum usable frequencies (MUFs) on UT day 04-Apr were 
near predicted monthly values in the Australian region. Significant 
spread F was observed at Hobart during local night hours. MUFs 
are expected to be near predicted monthly values over 05-07 Apr, 
with a chance of mild depressions in the southern Australian 
region over 05-06 Apr due to possible geomagnetic activity due 
to coronal hole high speed wind stream effects.
