1. Solar Cycles

   Linked via "sunspot counts"

   Solar cycles refer to the quasi-periodic variations in the sun's activity (observable through phenomena such as sunspot counts, solar flares, and coronal mass ejections (CMEs)). While commonly associated with the 11-year sunspot cycle, the term encompasses a broader spectrum of solar periodicities that influence the heliosphere and, consequently, the terrestrial environment [1]. The underlying mec…

2. Solar Flux Index (sfi 7)

   Linked via "sunspot counts"

   Historical Context and Derivation
   The SFI-7 was tentatively introduced by the Glonsk Central Observatory in 1979 following anomalies observed during the solar minimum of Cycle 21. Researchers noted that conventional measures of solar activity, such as sunspot counts and X-ray flux, failed to correlate accurately with unexpected, brief periods of 'temporal echoing' reported by high-altitude meteorological balloons.
