One commentator at this Universe Today post on Prometheus, moon of Saturn, sees this as a “kiss,” the interaction of the F Ring and the moon Prometheus

New images from Cassini show icy particles in Saturn’s F ring clumping into giant snowballs as the moon Prometheus makes multiple swings by the ring. The gravitational pull of the moon sloshes ring material around, creating wake channels that trigger the formation of objects as large as 20 kilometers (12 miles) in diameter.
Professor Carl Murray of the University of London:
Scientists have never seen objects actually form before. We now have direct evidence of that process and the rowdy dance between the moons and bits of space debris.
