2. FORECAST (11 NOVEMBER - 13 NOVEMBER)
Date   T index  Conditions       MUFs                              
11 Nov   140    Normal-poor      Initially enhanced with possible 
                                 depressions of 15-30% at times 
                                 later in the UT day. 
12 Nov    70    Poor-fair        depressed 15 to 30%/near predicted 
                                 monthly values     
13 Nov    90    Normal-fair      depressed 10 to 20%/near predicted 
                                 monthly values    
COMMENT: Increased absorption observed at Antarctic stations 
due to PCA event in progress. PCA event is expected to finish 
early on 11 November. HF conditions for low-mid latitudes are 
expected to be initially enhanced for 11 November with possible 
depressions of 15-30% later in the UT day of 11 November following 
the impact of a CME. Depressions are expected to continue at 
times for 12-13 November as geomagnetic activity continues.
