The movie displays a limb prominence above an active region observed with SOT/Hinode. Prominences are floating cool plasma in the hot corona. High resolution images in Ca II H spectral line revealed waving motion of the prominence. Detailed analysis proved that the motion is attributed to Alfvén wave in the corona. This observational result holds vital clues for understanding the coronal heating.
