Cassini ISS mutual event astrometry of the mid-sized Saturnian satellites 2005-2012

Cooper, N. J.; Lainey, V.; Murray, C. D. +3 more

Aims: We present astrometric observations of the Saturnian satellites Mimas, Enceladus, Tethys, Dione, and Rhea from Cassini Imaging Science Subsystem (ISS) narrow-angle camera (NAC) images. Image sequences were designed to observe mutual occultations between these satellites.
Methods: The positions of satellite centres were estimated by…

Multifrequency analysis of the Jovian electron-belt radiation during the Cassini flyby of Jupiter

Sault, R. J.; Janssen, M. A.; Bolton, S. J. +3 more

Aims: We examine Very Large Array (VLA) observations of Jupiter to present evidence of fluctuations in the emission produced by the electron belt in January 2001. Investigating the source of fluctuations will provide new opportunities to discuss the scenarios of temporal changes in Jupiter's synchrotron radiation (i.e., the electron belt) in …
