Statistical analysis of the plasmoid evolution with Geotail observations
Plasmoids in the Earth's magnetotail were studied statistically, using low energy particle (LEP) and magnetic field (MGF) data from the Geotail spacecraft. Their evolution along the tail axis fromExpand

Structure and dynamics of magnetic reconnection for substorm onsets with Geotail observations
Fast tailward ion flows with strongly southward magnetic fields are frequently observed near the neutral sheet in the premidnight sector of the magnetotail at 20–30 RE for substorm onsets in GeotailExpand

Association between Geotail plasma flows and auroral poleward boundary intensifications observed by CANOPUS photometers
Poleward boundary intensifications are nightside geomagnetic disturbances that have an auroral signature that moves equatorward from the poleward boundary of the auroral zone. They occurExpand

The Geotail Mission
This paper provides an overview of the GEOTAIL project, a joint effort by NASA and the Institute of Space and Astronautical Science (ISAS) of Japan. This article describes the spacecraft, theExpand

The Low Energy Particle (LEP) Experiment onboard the GEOTAIL Satellite
The low energy particle (LEP) instrument onboard GEOTAIL is designed to make comprehensive observations of plasma and energetic electrons and ions with fine temporal resolution in the terrestrialExpand

Formation of plasmapause, or magnetospheric plasma knee, by the combined action of magnetospheric convection and plasma escape from the tail
Magnetospheric convective system proposed by Axford and Hines is revised and made compatible with the view, based on the recently obtained geomagnetic data, that (1) the convective motion induced byExpand

Geomagnetic Dp 2 fluctuations and associated magnetospheric phenomena
A DP 2 fluctuation has a time scale of about one hour and appears coherently all over the world. It differs from the polar substorm (DP 1) in that it is not caused by the activation of the auroralExpand

Turbulent magnetic field in the distant magnetotail: Bottom‐up process of plasmoid formation?
The GEOTAIL magnetic field observations in the earth's magnetotail are examined in terms of a turbulent magnetic reconnection process. It is found that the observed Fourier power spectral density ofExpand

Coherence of geomagnetic DP 2 fluctuations with interplanetary magnetic variations
From the comparison of the worldwide geomagnetic data with IMP 1 magnetic records obtained in the interplanetary space, it is found that the DP 2 fluctuations, which are thought to be the geomagneticExpand
