Monthly SSN Sunspot-Numbers
IPS OBSERVED AND PREDICTED SOLAR INDICES
Prepared and Copyright by IPS Radio and Space Services Australia
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.
This page is updated monthly using observed monthly sunspot numbers from the Solar Influences Data Analysis Center (http://sidc.oma.be). Monthly values are smoothed using a 13 monthly running filter (first and last half weighting) and, where needed, combined with a predicted sunspot number curve for Cycle 24. Values which have an "e" next to them are based partly on observed and partly on predicted values. Values earlier in time to these are based entirely on observed values; values later in time are entirely predicted. Observed data are adjusted slightly at times to use the SIDC final monthly values which are available several months later - SIDC preliminary monthly values are used up to this time. All Solar Radio Flux values, including the "observed" values, are obtained from sunspot numbers using a statistical conversion. They are best described as equivalent solar flux values.
