2. FORECAST (11 JUNE - 13 JUNE)
Date   T index  Conditions       MUFs                              
11 Jun    80    Normal-Fair      near predicted monthly values

13 Jun    85    Normal           Near predicted monthly values    
COMMENT: Conditions mostly near normal at low to mid latitudes. 
Expect generally improving HF conditions after today, as high 
speed coronal hole wind stream effects decline. Antarctic regions 
will still experience periods of disturbance over the next few 
days. There is a possibilty of a proton induced absorption event 
at high latitudes within the next few days as a result of recent 
solar activity.
