Variation of Saturn's UV aurora with SKR phase
Cecconi, B.; Lamy, L.; Nichols, J. D. +6 more
It is well known that a wide range of kronian magnetospheric phenomena, including the Saturn kilometric radiation (SKR), exhibit oscillations near the planetary rotation period. However, although the SKR is believed to be generated by unstable auroral electrons, no connection has been established to date between diurnal SKR modulations and UV auro…
Dawn-dusk oscillation of Saturn's conjugate auroral ovals
Lamy, L.; Nichols, J. D.; Cowley, S. W. H.
We present observations of the oscillation of the dawn-dusk locations of Saturn's northern and southern UV auroral ovals obtained using the Hubble Space Telescope during the 2009 equinoctial campaign. We determine the dawn-dusk locations of the centers of the southern and northern auroral ovals from the mean of the dawnward and duskward extents of…
