Springer, thank you for the honor: i don't think to deserve it, but i'll put efforts in order to deserve it as soon as possible
And thanks also to ATSers for the kind words: this is the best community in the world, i'm proud to be a part of it.

Balez, not only you are right, but in this specific case, Saturn E rings have recently been found to
have been created by a Moon, Enceladus: have a star for your construction.
The animation kindly provided by olegkvasha definately shows the final part of an orbit, it's just the loop that creates the optical illusion of it
being a full orbit.
The appearance has been more er less explained: so what we see could likely be a moon.
We should wonder if it's a coincidence or not the fact that the jet comes visible once the body reaches the edge of the image: i mean, when the
camera ceases to be blinded by the bright of the object, but i don't know if this assestment will be seriously feasible before the calibration of the
images, since the actual appearance of all that we see is unknown.
IMHO, after the calibration we could find out that the jet is visible during the whole motion, (but i'm not sure).
In this case the jet could be dust particles after being hit by the body in transit: what looks to be empthy space, actually is not:
for example, this is E ring being hit by Enceladus:
It's hard to conclusively assest what the object is, since we have not enough data available and besides there's a lack of perspective:
if it's a Moon, and if what we see is saturn E ring, than the first options that come to my mind are Rhea and Enceladus (besides as said before, now
Enceladus is known to have created E ring and for its geysers).

The only facet of the geyser theory that doesn't convice me, is that the jet seems to come right from the center of the body, and that looks to be a
odd coincidence, to say the least, even if this could be explained with the speed of the body edmitting the "jet":as quick the body is travelling,
as more the jet would appear to be centered behind it.
Anyway, all these constructions may don't make sense, since they're based on non calibrated images.
