An empirical relationship between interplanetary conditions and Dst
An algorithm is presented for predicting the ground-based Dst index solely from a knowledge of the velocity and density of the solar wind and the north-south solar magnetospheric component of theExpand

A new functional form to study the solar wind control of the magnetopause size and shape
In this study a new functional form, r = r 0 [2/(1 + cos θ)] α , is used to fit. the size and shape of the magnetopause using crossings from ISEE 1 and 2, Active Magnetospheric Particle TracerExpand

Magnetopause location under extreme solar wind conditions
During the solar wind dynamic pressure enhancement, around 0200 UT on January 11, 1997, at the end of the January 6-11 magnetic cloud event. the magnetopause was pushed inside geosynchronous orbit.Expand

Statistical characteristics of bursty bulk flow events
Using a common methodology to analyze data from the AMPTE/IRM and ISEE 2 satellites the authors report on the statistical properties of bursty bulk flow events (BBFs) in the inner plasma sheet (IPS).Expand

Semiannual variation of geomagnetic activity
The semiannual variation in geomagnetic activity is well established in geomagnetic data Its explanation has remained elusive, however. We propose, simply, that it is caused by a semiannual variationExpand

Satellite studies of magnetospheric substorms on August 15, 1968. IX - Phenomenological model for substorms.
Observations made during three substorms on August 15, 1968, are shown to be consistent with current theoretical ideas about the cause of substorms. The phenomenological model described in severalExpand

Differentiation of the asteroid Ceres as revealed by its shape
The accretion of bodies in the asteroid belt was halted nearly 4.6 billion years ago by the gravitational influence of the newly formed giant planet Jupiter. The asteroid belt therefore preserves aExpand

Determining the standoff distance of the bow shock: Mach number dependence and use of models
We explore the factors that determine the bow shock standoff distance. These factors include the parameters of the solar wind, such as the magnetosonic Mach number, plasma beta, and magnetic fieldExpand

Near-Earth magnetotail shape and size as determined from the magnetopause flaring angle
Knowledge of the average size and shape of the near-Earth magnetotail is an essential element for our understanding of the magnetospheric response to the influence of the solar wind. An empiricalExpand
