Third contact ushered in a beautiful diamond ring effect. This 1/500 second exposure shows the (overexposed) photosphere emerging at the lower left as the Moon uncovers the face of the Sun. Even at this moment, the inner corona and prominences remain visible to the camera, although the dazzle of the diamond ring hides them from visual observers (who must, in any case, avert their eyes or use a safe solar filter from the instant totality ends).
