Although the 150-foot tower, under good observing conditions, should show the rotational displacements, it seemed probable that under average conditions a lower dispersion and smaller solar image might give better results.

  SDO is documenting solar events such as solar prominences, solar flares, coronal mass ejections and high-speed solar wind. A solar prominence is an enormous eruption of plasma from the sun's surface. Solar prominences often appear as loops—some so large that several Earth-sized planets could fit inside. A solar flare is a blast of radiation
