There are ubiquitous flows observed in the solar atmosphere of sub-Alfvenic speeds; however, after flaring and coronal mass ejection events flows can become Alfvenic. In this Letter, we derive an expression for the standing kink mode frequency due to siphon flow in coronal loops, valid for both low and high speed regimes. It is found that siphon flow introduces a linear, spatially dependent phase shift along coronal loops and asymmetric eigenfunctions. We demonstrate how this theory can be used…

TLDR
Four topics are focused on: the current controversy surrounding propagating intensity perturbations along coronal loops, the interpretation of propagating transverse loop oscillations, the ongoing search for coronal (torsional) Alfvén waves, and the rapidly developing topic of quasi-periodic pulsations in solar flares.

Kink Oscillations of Coronal Loops
Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy releases, such as low
