From the Gran Chaco of Paraguay, this magnificent "diamond ring" was shot only seconds before the total solar eclipse of November 3, 1994, as the final beam of sunlight shone over the lunar horizon.   It shows the moon silhouetted against the sun's inner corona, as well as the sun's pinkish chromosphere, only a few thousand miles deep.  Along the sun's edge arch several red prominences, the largest of which at the very top could engulf three Earths.
