Time variability of coronal funnels
Abstract
Transition region spectra from the network are commonly composed by two components: a narrow one from smaller loops and a broad tail component that can be interpreted as originating from coronal funnels. We present a time series analysis of tail components for one network region. A comparison of fitted spectra obtained by applying running means with full time resolution spectra shows that typical explosive events are not responsible for the observed tail components. The correlation between core and tail intensities on time-scales of minutes is not significant.
