[en] In this presentation we use bi-directional energetic electron distributions from the MIMI-LEMMS instrument
onboard Cassini, auroral observations from the Hubble Space Telescope (HST) and data from the UVIS
instrument onboard Cassini to characterize the open-closed field line boundary in Saturn’s magnetosphere. The
high-latitude open-closed field line boundary at Saturn is thought to be related to the main auroral ring of
emission of the planet varying in location, intensity and latitudinal extent as well as in its homogeneity. This
study extends the work on the plasmapause/open-closed field line boundary published by [1] by covering a
larger data set at different local times and comparing the electron distributions with auroral observations. Based
on energetic electron data we characterize the open-closed field line boundary in terms of temporal, local time
variations and other parameters and we correlate the Cassini in-situ measurements to the observations of the
main auroral ring at Saturn.
