The Location of Magnetic Reconnection at Earth's Magnetopause
Fuselier, S. A.; Trattner, K. J.; Petrinec, S. M.
One of the major questions about magnetic reconnection is how specific solar wind and interplanetary magnetic field conditions influence where reconnection occurs at the Earth's magnetopause. There are two reconnection scenarios discussed in the literature: a) anti-parallel reconnection and b) component reconnection. Early spacecraft observations …
Shock Induced Strong Substorms and Super Substorms: Preconditions and Associated Oxygen Ion Dynamics
Zong, Q. -G.; Fu, S. -Y.; Yue, C.
It is well known that the interaction between interplanetary (IP) shocks and the Earth's magnetosphere would generate/excite various types of geomagnetic phenomena. Progresses have been made on the Earth's magnetospheric response to solar wind forcing in recent years in the aspects associated with magnetospheric substorms. Strong substorms and sup…

Statistical Investigation of the Frequency Dependence of the Chorus Source Mechanism of Plasmaspheric Hiss
Shen, Xiao-Chen; Meredith, Nigel P.; Horne, Richard B. +2 more
We use data from eight satellites to statistically examine the role of chorus as a potential source of plasmaspheric hiss. We find that the strong equatorial (|λm| < 6°) chorus wave power in the frequency range 50 < f < 200 Hz does not extend to high latitudes in any magnetic local time sector and is unlikely to be the source o…
Cross-Scale Energy Transport in Space Plasmas: Applications to the Magnetopause Boundary

Observations of Closed Magnetic Flux Embedded in the Lobes During Periods of Northward IMF
Fear, R. C.; Coxon, J. C.; Fryer, L. J. +1 more
The high latitude, lobe regions of the magnetosphere are often assumed to contain cool, low energy plasma populations. However, during periods of northward Interplanetary Magnetic Field, energetic plasma populations have occasionally been observed. We present three cases when Cluster observed uncharacteristically "hot" plasma populations in the lo…
Turning Instrument Background Into Science Data for Structural Features of Radiation Belts
Dandouras, I.; Rème, H.; Liemohn, M. W. +2 more
Approaches regarding how to turn the instrument background counts into scientifically valuable data are presented in this Technical Report on Methods. The background counts due to penetrating energetic particles of radiation belts detected on Cluster CIS HIA and CODIF instruments and the Double Star HIA instrument are used in these approaches. In …
