Here are clumps as viewed by Cassini of bright patches or clumps in the
outer F ring that defy
explanation.
Actually, I wouldn't say that they defy explanation, as there have been
several theories proposed to account for them. One involves perturbations
by
one of the two shepherding satellites Pandora and Prometheus, which is
probably the most promising. Another is the existance of a smaller but as
of
yet undiscovered moon. Probably, when Cassini gets closer and studies the
F-ring in more detail, we will get more information to determine what is
going
on. Clear skies to you.
grasping at straws at best
