Open flux estimates in Saturn's magnetosphere during the January 2004 Cassini-HST campaign, and implications for reconnection rates [PDF]

, 2005
peer reviewedDuring 8-30 January 2004, a sequence of 68 UV images of Saturn's southern aurora was obtained by the Hubble Space Telescope (HST), coordinated for the first time with measurements of the upstream interplanetary conditions made by the Cassini

In situ local shock speed and transit shock speed [PDF]

Annales Geophysicae, 1998
A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]

, 2008
The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

What causes the variations of the peak intensity of CIR accelerated energetic ion fluxes? [PDF]

Annales Geophysicae, 1998
The variation of the peak intensity of energetic ions accelerated at CIR related shocks in the interplanetary medium as observed by instruments on board of ULYSSES during its pass towards the south polar region and from the north polar region back to ...

The Physical Nature of Interplanetary Dust as Inferred by Particles Collected at 35 km [PDF]

International Astronomical Union Colloquium, 1971
Particles were collected at an altitude of 35 km by two flights of a volume-sampling micrometeorite collector. The collection scheme is very sensitive and is capable of collecting a significant number of particles. Many of the particles collected have chemical compositions similar to solar or to iron meteorites.

Signature of Saturn's auroral cusp: Simultaneous Hubble Space Telescope FUV observations and upstream solar wind monitoring [PDF]

, 2005
peer reviewedModel simulations by Bunce et al. (2005a) have shown that direct precipitation of electrons in Saturn's dayside cusp regions is not capable of producing significant FUV aurora.

Magnetic topology of coronal mass ejection events out of the ecliptic: Ulysses/HI-SCALE energetic particle observations [PDF]

Annales Geophysicae, 2003
Solar energetic particle fluxes (Ee > 38 keV) observed by the ULYSSES/HI-SCALE experiment are utilized as diagnostic tracers of the large-scale structure and topology of the Interplanetary Magnetic Field (IMF) embedded within two well ...

Formation and motion of a transpolar arc in response to dayside and nightside reconnection [PDF]

, 2005
peer reviewed[ 1] We trace the formation and subsequent motion of a transpolar arc in response to dayside and nightside reconnection. Both high- and low-latitude dayside reconnection are observed, as well as periods of substorm and nonsubstorm nightside ...

Mutual information between geomagnetic indices and the solar wind as seen by WIND : implications for propagation time estimates [PDF]

, 2005
The determination of delay times of solar wind conditions at the sunward libration point to effects on Earth is investigated using mutual information. This measures the amount of information shared between two timeseries.

Multi-instrument observations of nightside plasma patches under conditions of IMF Bz positive [PDF]

, 2008
Results are presented from two multi-instrument case studies showing patches of cold, long-lived plasma in the winter nightside ionosphere during times when the z-component of the Interplanetary Magnetic Field (IMF Bz) was positive.
