Accuracy of multi-point boundary crossing time analysis [PDF]

Annales Geophysicae, 2011
Recent multi-spacecraft studies of solar wind discontinuity crossings using the timing (boundary plane triangulation) method gave boundary parameter estimates that are significantly different from those of the well-established single-spacecraft ...

Observed tail current systems associated with bursty bulk flows and auroral streamers during a period of multiple substorms [PDF]

, 2008
We present a multi-instrument study of a substorm bursty bulk flow (BBF) and auroral streamer. During a substorm on 25 August 2003, which was one of a series of substorms that occurred between 00:00 and 05:00 UT, the Cluster spacecraft encountered a BBF ...

Magnetopause current as seen by Cluster [PDF]

Annales Geophysicae, 2005
The four-spacecraft, magnetic field measurements on Cluster can be combined to produce an accurate determination of the electric current in the magnetopause boundary during stable magnetopause crossings.

Coordinated studies of the geospace environment using cluster, satellite and ground-based data: An interim review [PDF]

, 2005
A little more than four years after its launch, the first magnetospheric, multi-satellite mission Cluster has already tremendously contributed to our understanding about the coupled solar wind - magnetosphere - ionosphere system.

Near-simultaneous magnetotail flux rope observations with Cluster and Double Star [PDF]

Annales Geophysicae, 2007
We present observations of three magnetic flux ropes in the tail of the Earth's magnetosphere on 7 August 2004 by the Cluster and Double Star TC-1 spacecraft.

Four-spacecraft determination of magnetopause orientation, motion and thickness: comparison with results from single-spacecraft methods [PDF]

Annales Geophysicae, 2004
In this paper, we use Cluster data from one magnetopause event on 5 July 2001 to compare predictions from various methods for determination of the velocity, orientation, and thickness of the magnetopause current layer. We employ established as well as

An initial investigation of the long-term trends in the fluxgate magnetometer (FGM) calibration parameters on the four Cluster spacecraft [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2014
Over the course of more than 10 years in operation, the calibration parameters of the outboard fluxgate magnetometer (FGM) sensors on the four Cluster spacecraft are shown to be remarkably stable.

Coordinated Cluster/Double Star observations of dayside reconnection signatures [PDF]

Annales Geophysicae, 2005
The recent launch of the equatorial spacecraft of the Double Star mission, TC-1, has provided an unprecedented opportunity to monitor the southern hemisphere dayside magnetopause boundary layer in conjunction with northern hemisphere observations by ...

Cusp observations during a sequence of fast IMF B_Z reversals [PDF]

Annales Geophysicae, 2009
In recent years, a large number of papers have reported the response of the cusp to solar wind variations under conditions of northward or southward Interplanetary Magnetic Field (IMF) Z-component (BZ).
