Latest article available for the first revolution of the solstice mission here
A nice little squint at Daphnis (20-odd pixels in the NAC) accompanies a Titan flyby and 'propeller' studies amongst other things.
Thanks again Jason for the planned observation schedules.

Very long sequence of images on the Cassini website showing thumbnails (256x256 pixels) that appear to be an aurora sequence.
It'll be interesting to see what the Cassini/Ciclops team get out of this observation set this time around.
Here's an enlarged and noise-reduced frame...

How's her fuel holding up?

Cassini uses two types of fuel, hydrazine, which is used for small navigation maneuvers, and a standard bipropellant for larger maneuvers. While there is ample hydrazine to continue the mission through 2017, the Cassini navigation team has to be more conservative with its bipropellant. "We will design future tours knowing how much propellant is available for velocity change," Mitchell said.
Beautiful image of the rings... just beautiful...

Very interesting specular-like brightening around the tiger stripes in these images. Brighter patches were visible before, but I don't think I've ever seen the effect as pronounced as here (right hand image is just an enhancement).

If crystalline ice in the sulci is blue-green in the IR3/GRN/UV3 filter combo, what is white? Freshly fallen amorphous ice particles?

Possibly freshly condensed frost from vapor?
That's an interesting find, Gordan. I wonder if particle sizes can be determined in some way from the relfectance properties.
Large loose particles tend to be white/gray and highly scattering... In principle it is possible to determine particle size from wavelength-dependent scattering information, but for visible/uv wavelengths particles are quickly large compared to the wavelength (which is what counts), which makes it a lot harder with only visible images.

Definitely. Grain sizes can alter the detailed spectral shape. Water ice grains of different sizes have slightly different IR spectra.
Nice! 
Another one, July 15th:

Don't know which moon that is, might be Rhea judging by the color.
