2. FORECAST (07 JANUARY - 09 JANUARY)
Date   T index  Conditions       MUFs                              
07 Jan    20    Normal-fair      about 10% below predicted monthly 
                                 values 
08 Jan    20    Normal-fair      about 10% below predicted monthly 
                                 values     
09 Jan    30    Normal           Near predicted monthly values    
COMMENT: Frequencies were overall near monthly medians at southern 
mid-latitudes but depressed at northern near-equatorial latitudes. 
A geomagnetic disturbance from a coronal hole took effect from 
19UT and will likely affect the ionosphere during 7-8 Jan, suppressing 
MUFs with the effect spreading from polar towards equatorial 
regions. Sporadic-E is likely to continue over the next few days.
