2. FORECAST (10 JUNE - 12 JUNE)
Date   T index  Conditions       MUFs                              
10 Jun    70    Fair             Near predicted values/enhanced 
                                 equatorial/PNG region. Near 
                                 predicted monthly values with 
                                 mild overnight or post-dawn 
                                 depressions Aus/NZ regions. 
                                 Generally poor conditions in 
                                 Antarctic regions.

12 Jun    85    Normal           Near predicted monthly values    
COMMENT: Moderate overnight depressions observed S Aus regions. 
Extensive and occasionally intense sporadic-E and spread-F conditions 
observed S Ocean/Antarctic regions with absorption observed around 
local dawn. Expect similar localised conditions today. Degraded 
HF conditions expected next few days due to further coronal hole 
induced geomagnetic activity.
