We investigate the relationship between interdiurnal variation geomagnetic activity indices,IDVandIDV(1d), corrected sunspot number,RC, and the group sunspot numberRG.RCuses corrections for both the “Waldmeier discontinuity,” as derived in Paper 1, and the “Wolf discontinuity” revealed by Leussu et al. (2013). We show that the simple correlation of the geomagnetic indices withRCnorRGnmasks a considerable solar cycle variation. UsingIDV(1d) orIDVto predict or evaluate the sunspot numbers, the errors are almost halved by allowing for the fact that the relationship varies over the solar cycle. The results indicate that differences betweenRCandRGhave a variety of causes and are highly unlikely to be attributable to errors in eitherRGalone, as has recently been assumed. Because it is not known ifRCorRGis a better predictor of open flux emergence before 1874, a simple sunspot number composite is suggested which, likeRG, enables modeling of the open solar flux for 1610 onward in Paper 3 but maintains the characteristics ofRC.
