On September 9th 2004, Nasa announced the possible discovery of two new Saturnian moons, spotted by Carl Murray, from pictures taken just prior to Cassini orbit insertion. Both appear to orbit within 1000 kilometres of the F-ring. In the intervening two years, as far as I'm aware, there have been no follow-up press releases on these possible objects. Does anybody have any subsequent information on these? Possibly (as stated in the release) they were just short-lived agglomerations of ring material, although diameters were quoted as being in the region of 4-5 km
