I've just noticed on the NASA raw images page that a new camera target has appeared, named K07S4. A handful of images have been taken with both cameras using the clear filters since the end of December last year, but I can't see anything resolved in the images.
I wonder what they're looking for? another Methone/Pallene-zone moon perhaps??
The recent 'looking ahead' page on CICLOPS mentions a search in this area soon, but I can't find anything prior to that.

Most likely they're looking for a shepherd moon like you said jasedm.

Say have you noticed these bright spots in the F ring --> http://saturn.jpl.nasa.gov/multimedia/imag...iImageID=140491

K07S4 = 2007 S 4 = Anthe

Is Anthe markedly non-spherical?
Or is the below image a result of imaging artefact/smearing? (star trails indicate a longish exposure time)
Other shots taken on the same day (12th October this year) show no elongation, but perhaps Anthe rotates pretty fast.

Cropped, enlarged, and darkened:

That looks like a long exposure so there might have been some tracking smear, rather than resolved image to me.
