Hemispheric Sunspot Numbers 1975-2000
Listed in IVOA Registry (Virtual Observatory)
Hemispheric sunspot numbers including the time span from 1975-2000 are presented.
Description
The Sunspot Numbers are calculated from sunspot drawings made at the Kanzelhoehe Solar Observatory (KSO), Austria. The counted northern and southern Sunspot Numbers are normalized and multiplied with the International Sunspot Numbers taken from SIDC for matching days in order to provide the data within an international usage.
Days without observation by KSO (about 27 percent) were reconstructed applying a linear interpolation method. As validation of the data, regression methods and a cross-correlation analysis are made with hemispheric Sunspot Numbers from SIDC for the available time span 1992-2000 obtaining very good agreements. The results are given in monthly mean and smoothed monthly mean Sunspot Numbers.
