Daphnis cruises through the Keeler Gap, raising edge waves in the ring material as it passes.
As is characteristic of waves raised by a moon on the edges of a very narrow gap like Keeler, the wave begins as a coherent form near Daphnis and becomes less so with increasing orbital distance from the moon. Daphnis is 7 kilometers (4.3 miles) across.
This view looks upon the lit side of the rings from about 31 degrees below the ringplane.
