The values in the smoothed sunspot number table are based on the observed    
(definitive and provisional) monthly mean sunspot numbers from WDC-SILSO,    
Royal Observatory of Belgium, Brussels (sidc.oma.be/silso/home).             
                                                                             
In June 2015, WDC-SILSO, Royal Observatory of Belgium, Brussels, adjusted    
their original observed sunspot numbers (Version 1.0) to a Version 2.0       
series in which the sunspot numbers are higher. In the Version 1.0 data      
series, some of the sunspot numbers were weighted. The new (Version 2.0)     
sunspot numbers are unweighted sunspot number counts. The Bureau of          
Meteorology SWS solar cycle prediction is now based on the Version 2.0       
values.                                                                      
                                                                             
The values in the smoothed 10.7 cm solar flux table are derived from daily   
10.7 cm solar flux values adjusted to 1 Astronomical Unit (A.U.). The daily  
values are averaged to provide monthly mean values which are then smoothed.  
The 10.7 cm solar radio flux data are provided as a service by the National  
Research Council of Canada.                                                  
                                                                             
In both tables, the observed monthly mean values are smoothed using a 13-    
month running filter (the values for the 1st and 13th months have half the   
weighting). Estimated values have an "e" suffix and are calculated from      
observed monthly and predicted smoothed numbers. Observed smoothed values    
precede the estimated values while predicted smoothed values follow the      
estimated values. If no estimated values are shown, all values are observed  
smoothed values and no prediction is shown.
