Details for this revolution are available here

This is the orbit I've been looking forward to for some time as it affords us a closer glimpse at Atlas, Prometheus and Epimetheus.

In fact, Cassini approaches the latter two at a closer range than it will for the remainder of the mission, and observations are planned for both, as well as Atlas.
This, despite having to turn the spacecraft and use the high-gain antenna as a shield during ring-plane crossing to avoid any possible collisions with debris in the ring-plane.

This must have been an extra-specially complicated sequence of observations to plan, as it all happens at or around periapse.

I'm really looking forward to another view of Atlas particularly - can't wait!!!

Looking at the PDS data for this medium-range flyby of Atlas, I realized a number of frames at the start of the sequence were taken against the backdrop of Saturn's night-side. Thanks to the faint illumination of the cloud decks with ring-shine, an extreme contrast stretch of the images reveals the moon's equatorial bulge and southern hemisphere in profile.
