Show moreRecent velocity imaging observations obtained with the Coronal Multi-channel Polarimeter (CoMP) instrument reveal the existence of ubiquitous propagating Alfvén waves in the solar corona. These data present an exciting opportunity for probing the structure and magnetic topology of the coronal plasma through coronal seismology. We present the results of a time-distance analysis of the wave observations which allows the determination of the phase speed of the waves and the relative quantity of outward and inward wave flux. This analysis also provides a k-omega diagnostic diagram of coronal waves. We discuss current and future prospects for coronal seismology with these data. Show less
