The Variation of Solar Chromospheric H-alpha Plage 2002-2009
Abstract
Solar Chromospheric Plages in H-alpha represent a thermal dissipative response to the underlying magnetic field. In this study we track the daily variation of active region and quiet-sun plages areas and the underlying magnetic fields, during 2002-2009. In this poster, we present the methodology used to understand this variation as a function of the magnetic field. We present variations of plage intensities and ares over the solar cycle and examine their cyclical and non-cyclical patterns.
