2. FORECAST (30 NOVEMBER - 02 DECEMBER)
Date   T index  Conditions       MUFs                              
30 Nov    70    Normal           Near predicted monthly values
01 Dec   120    Normal           About 20% above predicted monthly 
                                 values    
02 Dec   130    Normal           About 30% above predicted monthly 
                                 values   
COMMENT: MUF enhancements of between 20-40% were observed across 
the region over the last day. The geomagnetic disturbance experienced 
during the first half of the day did not significantly impact 
the MUFs. However, northern and some central sites are observing 
reduced MUFs after local dawn than have been experienced recently, 
with some levels depressed below predicted monthly values. This 
is potentially a result of the geomagnetic activity and suggests 
MUFs will be reduced from the recently enhanced values for the 
next day or two before recovering. Due to the current strength 
of the ionosphere, the MUFs are still expected to be around predicted 
monthly values at worst before becoming enhanced again on days 
2 and 3.
