2. FORECAST (17 APRIL - 19 APRIL)
Date   T index  Conditions       MUFs                              
17 Apr   100    Normal           Near predicted monthly values

COMMENT: HF propagation conditions are good with MUFs at or exceeding 
predicted monthly values. The ionising solar EUV flux is elevated 
with numerous visible sunspot regions which should maintain the 
current levels of ionospheric support for HF over the forecast 
period.
