I was referring to the bright streak containing three brighter peaks that is very prominent in the middle of the rings, starting roughly below the rightmost limb of Enceladus and extending towards the right.

Oh, that. Since it's too far past equinox to show any dramatic ring topography, my WAG would be that's a clump of forward-scattering dust in an otherwise pretty empty region. What is that, anyway - Cassini division?

OK, sounds good, but I didn't know there were localised clumps of material like that in the Cassini Division (if that's indeed the location). I was thinking something out-of-plane might appear brighter by being more directly illuminated - maybe a spoke-type feature or moon wake?? It's pretty striking anyhow.

My guess is that it's clumping caused by either Pan or Daphnis as shown in this shot (which shows brightening caused by both moons)
