These tables 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). The observed values are smoothed using a 13 month  
running filter (the first and last values have half weighting). Estimated    
values have an "e" suffix and are calculated from observed monthly and       
predicted smoothed sunspot numbers. Observed smoothed values precede the     
estimated values while predicted smoothed values follow the estimated values.
                                                                             
The 10.7 cm solar radio flux values, including the "observed" values, are    
obtained from sunspot numbers using a statistical conversion. They are       
therefore described as "equivalent" solar radio flux values.                 
                                                                             
SPECIAL NOTE                                                                 
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 (for more information see:              
www.sidc.be/silso/home). The Bureau of Meteorology SWS solar cycle prediction
is now based on the Version 2.0 values. As a result of the WDC-SILSO         
recalibration, the observed monthly sunspot numbers are higher. This is also 
reflected in the tables of smoothed sunspot numbers and equivalent 10.7 cm   
solar flux and the solar cycle graph.
