Description:
From sunspot drawings provided by the Kanzelhoehe Solar Observatory,
Austria, and the Skalnate Pleso Observatory, Slovak Republic, a data
catalogue of hemispheric Sunspot Numbers covering the time span
1945-2004 is extracted. The validated catalogue includes daily,
monthly-mean and smoothed-monthly relative sunspot numbers for the
northern and southern hemispheres separately and is available for
scientific use. Based on this data set an analysis concerning the
North-South asymmetry is made within this paper.
