Twenty earths, end-to-end, could fit along the lenght of this prominence. The images, taken on consecutive days, show some of the changes that occur from day-to-day in the suns's chromosphere. Two of my students took part in the observing/imaging/processing of these images. Hooray for what appears to be the end (last Dec.?) of solar minimum.
