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 the
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 Tracer

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.
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).
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 variation
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 several
Differentiation of the asteroid Ceres as revealed by its shape
C Ceres has a shape and smoothness indicative of a gravitationally relaxed object that is significantly less flattened than that expected for a homogeneous object, but is consistent with a central mass concentration indicative of differentiation.
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 field
The Magnetospheric Multiscale Magnetometers
To achieve mission objectives, the calibration determined on the ground will be refined in space to ensure all eight magnetometers are precisely inter-calibrated, and the information flow that provides the data on the rapid time scale needed for mission success is described.
