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.
