Journal ArticleDOI
Response of Jupiter's and Saturn's auroral activity to the solar wind
John Clarke,Jonathan D. Nichols,Jean-Claude Gérard,Denis Grodent,Kirk C. Hansen,William S. Kurth,G. R. Gladstone,J. Duval,S. Wannawichian,Emma J. Bunce,Stanley W. H. Cowley,F. J. Crary,Michele K. Dougherty,Laurent Lamy,Donald G. Mitchell,Wayne Pryor,Kurt D. Retherford,Tom Stallard,Bertalan Zieger,Philippe Zarka,Baptiste Cecconi +20 more
TL;DR: A large campaign of observations of these planets has been undertaken using the Hubble Space Telescope, in association with measurements from planetary spacecraft and solar wind conditions both propagated from 1 AU and measured near each planet as mentioned in this paper.
Journal ArticleDOI
Morphological differences between Saturn's ultraviolet aurorae and those of Earth and Jupiter
John Clarke,Jean-Claude Gérard,Denis Grodent,S. Wannawichian,Jacques Gustin,John E. P. Connerney,F. J. Crary,M. K. Dougherty,William S. Kurth,Stanley W. H. Cowley,Emma J. Bunce,T. W. Hill,Jungeol Kim +12 more
TL;DR: In this article, the authors report ultraviolet images of Saturn, which, when combined with simultaneous Cassini measurements of the solar wind and Saturn kilometric radio emission, demonstrate that its aurorae differ morphologically from those of both Earth and Jupiter.
Journal ArticleDOI
Oscillation of Saturn's southern auroral oval
Jonathan D. Nichols,Jonathan D. Nichols,John Clarke,Stanley W. H. Cowley,J. Duval,Alison J. Farmer,Jean-Claude Gérard,Denis Grodent,S. Wannawichian +8 more
TL;DR: In this article, the center of the auroral oval oscillates with period 10.76 h ± 0.15 h for both January 2007 and February 2008, i.e., close to the periods determined for oscillations in other magnetospheric phenomena.
Journal ArticleDOI
Saturn's equinoctial auroras
Jonathan D. Nichols,Sarah V. Badman,Emma J. Bunce,John Clarke,Stanley W. H. Cowley,F. J. Crary,M. K. Dougherty,Jean-Claude Gérard,Denis Grodent,Kirk C. Hansen,William S. Kurth,D. G. Mitchell,Wayne Pryor,Tom Stallard,D. L. Talboys,S. Wannawichian +15 more
TL;DR: For example, Nichols et al. as discussed by the authors showed that the radius of the northern auroral oval is 1.5 smaller than the southern, indicating that Saturn's polar ionospheric magnetic field, measured for the first time in the ionosphere, is � 17% larger in the north than the south.
Journal ArticleDOI
Interaction evidence between Enceladus' atmosphere and Saturn's magnetosphere
TL;DR: In this paper, a search for Enceladus' auroral footprint using series of UV images of Saturn's aurora taken by the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) in January 2004 and the Advanced Camera for Surveys (ACS) between February 2005 and January 2007 was conducted.
