Evolvement of the Ring Current During a Magnetic Storm: TC-2 Neutral Atom Imager Observations
Shen, Chao; Liu, Zhen-Xing; Lu, Li +3 more
A series of ENA images were obtained by the NUADU instrument aboard TC-2 during a strong, long duration magnetic storm that occurred in November 2004. This paper follows the evolution of the ring current during this magnetic storm. It is shown that the southward IMF Bz component plays a key role in facilitating ion injection from the magnetotail i…
The ULF wave in the pile-up and dipolarization process
Liu, Zhen-Xing; Shi, Jian-Kui; Wang, Ji-Ye +3 more
A typical substorm process in the night-side near-Earth magnetotail company with the pile-up and depolarization process explored by TC-1 on sep 17, 2004. We analyzed the FGM and HIA data(4s resolution) with wavelet and FFT analysis method to understand the low-frequency wave in the pile-up and dipolarization process. The analysis results showed th…
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. …
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…
Further Study of Multiple Flux Rope Events at the Magnetopause Observed by TC-1 on 18 March, 2004

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…
