This data has been extracted and saved here for historical purposes so it will not be lost again. These are indeed SMOOTHED SSN to be used in the propagation prediction programs. 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/monthlyssnplot). 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. -------------------------- SMOOTHED SUNSPOT NUMBER ------------------------- Year Jan
