This color-enhanced image shows the dark spoke-like features in the rings. The spokes seem to form very rapidly with sharp edges and then dissipate. The A ring appears as the outermost bands but in this image appears as two bands divided by the Encke's division. The Cassini's division divides the A and B bands.
