Helmet Streamers

Caption

Mason searched for coronal rain in helmet streamers like the one that appears on the left side of this image, taken during the 1994 eclipse as viewed from South America. A smaller pseudostreamer appears on the western limb (right side of image). Named for their resemblance to a knight's pointy helmet, helmet streamers extend far into the sun's faint corona and are most readily seen when the light from the sun's bright surface is occluded.
