2. FORECAST (28 MAY - 30 MAY)
Date   T index  Conditions       MUFs                              
28 May     5    Normal           Near predicted monthly values
29 May    -5    Normal           Near predicted monthly values    
30 May     0    Normal           Near predicted monthly values   

COMMENT: MUFs were mostly near predicted monthly values for most 
AUS/NZ regions on UT day 27 May. Expect mostly near predicted 
monthly values for the next three UT days (28-30 May). The ionospheric 
support is expected to be slightly better today, but still near 
monthly predicted levels. This is in to response to the onset 
of possible minor magnetic disturbance associated with the passage 
of the polar coronal hole.
