Spoke-like features are visible in several recent wide angle images of the rings:
http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80037 http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80036 http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80034 These are high-phase views so any spokes should be brighter than the rings. And indeed there is a bright, narrow, vertically elongated feature visible in the B ring in several images that *might* be spokes. On the negative side there's this: http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80041 http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80031 http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=80032 Nothing obvious here so the spoke-like feature might be due to something else, for example scattered light within the camera - it's suspicious that the camera is pointing in a slightly different direction in these images. Another possibility is that the images were obtained at different times - the spokes vary with time. It will be interesting to see if these features are spokes or not. |

Hello all !
new images on the Raw site (images W00016526-29) has shown further spokes seen together in my small animated gif.  Robert
