2. FORECAST (23 APRIL - 25 APRIL)
Date   T index  Conditions       MUFs                              
23 Apr    10    Fair-poor        Near predicted monthly values

25 Apr     5    Fair             Near predicted monthly values   

COMMENT: For the UT day, 22 April, MUFs over the Australian region 
were mostly at enhanced levels compared to the monthly predicted 
value. MUF enhancements are typical on Day 1 of storming during 
this time of the year. The outlook for the next two days (23 
and 24 April) is for MUF levels to drop, but will still remain 
near monthly predicted levels. The degradations of MUFs are due 
to the storm induced ionospheric depression, which is expected 
to spread equatorwards from the polar regions over the next two 
days.
