A quantitative, static, empirical model of the high-latitude magnetopause is developed for GSM coordinates and parameterized by dipole tilt angle (ψ), solar wind pressure, and interplanetary magnetic field (IMF) Bz. We fit 691 high-latitude magnetop

We report comprehensive statistical results for 4 years of Hawkeye observations totaling 1757 boundary crossings. Our objective is to use the full set of Hawkeye plasma, magnetic field, and plasma wave data to identify every cusp-associated data inte

Energetic ∼10–210 keV/e low-charge-state heavy ions (LCSHI) were measured sunward of Earth's bow shock (to X ∼ 30 RE) during numerous intervals lasting from minutes to hours using Geotail/STICS in 1995–1998. LCSHI fluxes are strong and contin

A flux rope was detected in the near-Earth magnetotail at X ≃ -20 R E by Geotail with simultaneous viewing of the northern polar region by Polar on January 11, 1997. This offers the opportunity to ascertain the optical signature in the ionosphere o

We present an initial report on the first direct, concurrent measurements of solar wind oxygen (O) charge state variations inside and outside Earth's magnetosphere. On 10-11 Jan 1997 a magnetic cloud, with a spatial scale of at least ∼100 RE engulf

Measurements from the energetic particles and ion composition (EPIC) instrument on Geotail are used to investigate the relative abundance of different ion species at energies ∼10 keV to 3 MeV in flux ropes or plasmoids detected at various downstrea

We present here for the first time observations of the inverse correlation between the ion temperature anisotropy and plasma beta in the Earth's high-latitude magnetosheath. Hot proton data with energies of 0.3–8 keV were obtained from magnetosheat

Hawkeye plasma, magnetic field, and plasma wave instruments directly sampled the throat of the northern polar cusp as the orientation of the Interplanetary Magnetic Field (IMF) changed from southward to northward on July 3, 1974. Two distinct regions

Previous transport models of the plasmasphere, ring current and radiation belts have considered either diffusive or convective transport, but not both. Since the ∇B drift speed is proportional to energy, analyses of particles with E > 100 keV have

Reconnection is accepted as an important process for driving the solar wind/magnetospheric interaction although it is not fully understood. In particular, reconnection for northward interplanetary magnetic field (IMF) at high-latitudes tailward of th
