Differences between CME‐driven storms and CIR‐driven storms
Twenty one differences between CME-driven geomagnetic storms and CIR-driven geomagnetic storms are tabulated. (CME-driven includes driving by CME sheaths, by magnetic clouds, and by ejecta;Expand

The occurrence rate of magnetospheric‐substorm onsets: Random and periodic substorms
Particle-injection events are monitored on three geosynchronous satellites to determine the occurrences of magnetospheric substorms: for every consecutive pair of substorms found, the time intervalExpand

The Earth's plasma sheet as a laboratory for flow turbulence in high-β MHD
The bulk flows and magnetic-field fluctuations of the plasma sheet are investigated using single-point measurements from the ISEE-2 Fast Plasma Experiment and fluxgate magnetometer. TenExpand

Auroral arc thicknesses as predicted by various theories
Twenty-two theoretical mechanisms for auroral arcs are examined (12 electron-acceleration mechanisms and 10 generator mechanisms) and a characteristic auroral-arc thickness is worked out for eachExpand

Dominant role of the asymmetric ring current in producing the stormtime
Three storms are examined to determine the contribution to the Dst* index from the symmetric and asymmetric (partial) components of the ring current. The storms (September 24–25, 1998, October 18–19,Expand

The superdense plasma sheet: Plasmaspheric origin, solar wind origin, or ionospheric origin?
A few times per month, the density of the plasma sheet is several times higher than its usual density. Such superdense plasma sheet intervals are observed both in the midtail region and atExpand

Plasma sheet access to geosynchronous orbit
One year's worth of magnetospheric plasma analyzer data from three Los Alamos geosynchronous satellites are used for a statistical study of proton and electron fluxes at geosynchronous orbit andExpand

Low‐degree structure in Mercury's planetary magnetic field
[1] The structure of Mercury's internal magnetic field has been determined from analysis of orbital Magnetometer measurements by the MESSENGER spacecraft. We identified the magnetic equator on 531Expand

Geomagnetic storms driven by ICME- and CIR-dominated solar wind
The interaction of the solar wind and the Earth's magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejectionsExpand
