Global view of dayside magnetic reconnection with the dusk-dawn IMF orientation: A statistical study for Double Star and Cluster data
Lucek, E.; Dunlop, M. W.; Rème, H. +14 more
Double Star/TC-1 and Cluster data show that both component reconnection and anti-parallel reconnection occur at the magnetopause when the interplanetary magnetic field (IMF) is predominantly dawnward. The occurrence of these different features under these very similar IMF conditions are further confirmed by a statistical study of 290 fast flows me…
Flow burst-induced Kelvin-Helmholtz waves in the terrestrial magnetotail
Zhang, T. L.; Glassmeier, K. -H.; Lucek, E. +7 more
The Kelvin-Helmholtz instability (KHI) on the boundary of a flow channel in the Earth's plasma sheet is investigated using Cluster and Double Star TC1 data. It is shown that when Cluster moves into the flow channel the magnetometer measures strong oscillations of the magnetic field, that increase as the spacecraft move further into the flow channe…
TC-1 observations of flux pileup and dipolarization-associated expansion in the near-Earth magnetotail during substorms
Escoubet, C. P.; Dandouras, I.; Zhang, H. +16 more
Fifty-three substorms measured by Double Star/TC-1 in the near-Earth magnetotail from July to October, 2004 are studied. The main features of these events are: (a) Magnetic flux pileup characterized by continuous enhancement of B z is observed, which starts almost simultaneously with aurora breakup within 1-3 minutes, indicating that …
Observation of repeated intense near-Earth reconnection on closed field lines with Cluster, Double Star, and other spacecraft
Sauvaud, J. -A.; Zhang, T. L.; Glassmeier, K. -H. +14 more
We report strong repeated magnetic reconnection pulses that occurred deep inside closed plasma sheet flux tubes at r ≤ 14Re. They have been observed with a fortuitous spacecraft constellation during three consecutive turbulent magnetic dipolarizations, accompanied by localized auroral brightenings near the equatorward edge of a wide auroral oval. …
TC1 and Cluster observation of an FTE on 4 January 2005: A close conjunction
Pitout, F.; Wei, Y.; Dandouras, I. +20 more
Observations of a Flux Transfer Event (FTE) signature at the dayside magnetopause are reported, which was consecutively observed on 4 January 2005 by both the Double Star/TC1 spacecraft and the Cluster quartet, while the spacecraft were traversing through the northern-dusk magnetopause. The event occurred as a magnetosheath FTE first at the Cluste…
Near-simultaneous magnetotail flux rope observations with Cluster and Double Star
Wilson, R. J.; Dandouras, I.; Lucek, E. +6 more
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. The first two flux rope signatures were observed, near-simultaneously, by Cluster and TC-1, which were located at (-16.3, -8.7, 0.10) RE GSM and (-10.3, -7.11, 0.81) RE…
Plasma sheet stretching accompanied by field aligned energetic ion fluxes observed by the NUADU instrument aboard TC-2
Barabash, S.; Zhang, T. L.; Carr, C. M. +6 more
The NUADU (NeUtral Atom Detector Unit) instrument aboard TC-2 recorded 4л solid angle images of charged particles (E >180 keV) spiraling around the magnetic field lines in the near-Earth plasma sheet (at -7 RE, equatorial dawn-to-night side) during a geomagnetic storm (Dst =-219 nT) on August 24, 2005. Energetic ion beam events characterized b…
Double Star TC-1 observation of the earthward flowing plasmoids in the near magnetotail
Reme, H.; Shen, Chao; Carr, C. M. +4 more
We analyze Double Star TC-1 magnetic field data from July to September in 2004 and find that plasmoids exist in the very near-Earth magnetotail. It is the first time that TC-1 observes the plasmoids in the magnetotail at X > -13 RE. According to the difference of the magnetic field structure in plasmoids, we choose two typical cases for our stu…
Dipolarization Observed by TC1 and Cluster During Substorm in Sep. 14, 2004
Dunlop, M. W.; Reme, H.; Korth, A. +12 more
We study the substorm dipolarization occurring from 1730 to 1930 UT on Sep 14, 2004 based on DSP/TC1, Cluster and Polar data, combined with the aurora and geosynchronous energetic particle measurements and ground-based magnetic field observations. During this time period the IMF was continuously southward. Substorm onset started at about 1822 UT. …
Continuous tailward flow in the near-Earth magnetotail observed by TC-1 satellite
Shen, Chao; Zhang, LingQian; Liu, ZhenXing +2 more
On July 11, 2004, a substorm process in the period of continuous tailward flow was observed by the joint exploration of the TC-1, IMAGE and ACE satellites. The substorm observed by the TC-1 in the near-Earth has three stages: the growth phase (from 11:43 to 12:19), the pre-expansion process (from 12:19 to 12:28) and the dipolarization process. The…
