Dynamics of the Quiet Solar Chromosphere

Abstract

The solar chromosphere has never been static although it was often modeled so.Even the quiet-sun internetwork chromosphere has become thoroughly dynamic with the acoustic shock interpretation of the Ca II K 2V grains. We concentrate on the latter in this brief review. Recent analysis of ASP data confirms that their excitation is more likely set acoustically than magnetically.TRACE imagery permits seeing-free studies of their occurrence patterns.
