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 …
Relations Between Bursty Bulk Flows in the Magnetotail and Substorms
Dandouras, I.; Reme, H.; Cao, Jin-Bin +3 more
By using the data of three satellites of Cluster from 2001 to 2002, we study BBFs in the magnetotail and its relation to substorms. It is found that sometimes one or two of three satellites have already observed the BBF, and however the rest haven't. The reasons are as follows: (1) while the bulk flows satisfy the selection criterion of BBFs, the …
Further Study of Multiple Flux Rope Events at the Magnetopause Observed by TC-1 on 18 March, 2004
Pu, Zu-Yin; Xiao, Chi-Jie; Liu, Zhen-Xing +3 more
From 23:10 to 23:50 UT on 18 March 2004, the Double Star TC-1 spacecraft detected nine flux ropes at the outbound crossing of the southern dawnside magnetopause. During this time period the Cluster constellation was staying in the magnetosheath. The four spacecraft observed that the interplanetary magnetic field (IMF) showed a dominant negative BY…
Movement of the Magnetic Structure in the Plasma Sheet Observed by Cluster II
Balogh, A.; Reme, H.; Lu, Li +3 more
Using the data of the FGM instrument onboard of Cluster II, we can calculate the velocity of the magnetic structure. Data observed by Cluster II in the plasma sheet were analyzed during the storm (1 and 2 August, 2002) and the geomagnetism quiet (6 and 7 August, 2002) in GSM (Geocentric Solar Magnetospheric System) coordinates. After analyzing the…
Multipoint Analysis of the Temporal Scale of Bursty Bulk Flow Events during the Quiet Time of Magnetotail
Dandouras, I.; Reme, H.; Cao, Jin-Bin +3 more
A series of Bursty Bulk Flow events (BBFs) were observed by CLUSTER satellites during the quiet time of the magnetotail in 2001. The data of multi-satellites of CLUSTER show that the duration of BBFs observed by multi-satellites is longer than that of BBFs previously observed by single satellite. The duration of multi-satellites is about twice tha…
A Study of Orientation and Motion of Flux Transfer Events Observed at High-Latitude Dayside Magnetopause
Balogh, A.; Daly, P. W.; Reme, H. +4 more
This paper investigates 13 FTEs, which were detected by Cluster II in magnetosheath near the cusp region during February to March 2001. The orientation of the FTE tube axis is derived by virtue of minimum variance analysis (MVA) using magnetic field data from the four Cluster spacecraft. Of the 13 events, 6 axis directions are determined reliably,…
Multiple Flux Rope Events at the High-Latitude Magnetopause on January 26, 2001: Current Density Calculation
Glassmeier, K. -H.; Shen, Chao; Cao, Jin-Bin +12 more
A systematic comparison is carried out for three methods of current density calculation based on simultaneous magnetic field measurements of four-spacecraft Cluster mission. It is demonstrated analytically and numerically that within the linear approximation, all these methods lead to exactly the same results. As a case study, the current density …
A Study on the Characteristics of the Flux Transfer Events Occourred on March 2, 2001
Liu, Zhen-Xing; Shi, Jian-Kui; Jin, Shu-Ping +2 more
Three flux transfer events (FTEs) were detected in magnetosheath near the south cusp of the dawn side by Cluster II during the interval from 11:00 to 11:15UT on March 2nd, 2001. In this paper, we analyze the magnetic morphology and the plasma characteristics of these events using the magnetic field and plasma data observed by the four spacecrafts …
