The magnetic phenomena on the solar surface have been the subject of several investigations over the last 400 years. The early indicator of the solar magnetic activity was the sunspot counting. Currently, the main sunspot indicators are the International Sunspot Number, the Sunspot Group Number, the Total Sunspot Area, and the Photometric Sunspot Index. Several improvements in observational techniques have allowed measuring the magnetic activity using solar/stellar spectra.
