Chromosperic oscillations

Abstract

This review concentrates on the quiet-Sun chromosphere. Its internetwork areas are dynamically dominated by the so-called chromospheric three-minute oscillation. They are interpretationally dominated by the so-called Ca II K 2V and H 2V grains. The main points of this review are that the one phenomenon explains the other (both ways), that the quiet-Sun chromosphere is a clapotisphere per- vaded by shocks above h = 1 Mm, and that the existence of the classical temperature minimum is in doubt
