The ciclops "looking ahead" article for Rev 114 says that Cassini will take astrometric observations of "several of Saturn's small satellites including Pandora, Atlas, Janus, Methone, and Pallene". It doesn't say how close Cassini will come to these moons - will it get any data about the moons themselves (like brightness or albedo observations), or just orbital data?

Now I'm wrong, it looks, that we haven't good image of Methone. I mistake Methone with Pallene.
Best to date image of Methone is probably N1496907282 from distance 224 063 km (resolution 1.34 km/pix).
So Methone is only 2 - 3 pixels wide.
