Whistle and Hall Magnetic Field Associated with Near-Earth Magnetotail Reconnection Observed by Cluster
Santolik, O.; Reme, H.; Cao, Jin-Bin +4 more
During the period of 2001 2003, Cluster passed through the near-Earth magnetotail, and observed 14 magnetotail reconnection events. Simultaneously, Cluster observed electromagnetic wave associated with reconnection events. These 14 events can be classified into three categories: (1) Category 1: wave activities prior to and during reconnection even…
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. …
Multipoint Analysis of the Rapid Convection Event
Dandouras, I.; Lucek, E.; Reme, H. +4 more
Basing on the data from three satellites of Cluster (C1, C3 and C4) in the years of 2001 and 2002, we examine the relationship between the rapid convection event (RCE) and substorm. The observation of RCE measured by single satellite can not exactly describe what happens in the magnetotail. Both C1 and C3 observed the event occurring on July 25, 2…
The statistical characteristics of the tailward flows in the near-Earth region explored by TC1
Shen, Chao; Wang, Ji-Ye; Zhang, Ling-Qian +3 more
During quiet time and substorm process, tailward flow often explored in the near-Earth magnetotail by TC-1 satellite. The tailward flow is most strong near the equator, and stronger in the dusk-side and dawn-side than that in the night-side. The tailward flow tends to move from the dusk-side and dawn-side to the night-side, and becomes stronger wh…
Cluster Observation and Analysis of Bifurcation Current Sheet Structure in a Quiet Time
Lu, Li; Tang, Chao-Ling; Li, Zhong-Yuan
We analyse the vertical structure of the magnetotail current sheet during 2011 2030 UT on 19 August 2001, during which the Cluster spacecrafts crossed the current sheet in a quiet time. In the intervals, the current sheet moved slowly, and the value of the AE index was relatively small, about 40 130 nT. In the quiet time, without fast plasma flow …
