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 evolution of a complex solar radio burst corresponding to special configuration of microwave sources

Liu, Y. Y.; Xie, R. X.; Ren, D. B.

A complex radio burst associated with periodic (∼1 and 6 min) pulsations and several kinds fine structures, e.g., normal- and reverse-drifting type III bursts, zebra patterns, and slowly drifting structure was observed with the radio spectrometers (1.0-2.0, 2.6-3.8, 5.2-7.6, and 0.65-1.5 GHz) at the National Astronomical Observatories of China (NA…

Constraints on Simplified Quartessence Cosmology from the Latest Observational Data

Wu, Puxun; Dong, Sumei

The simplified generalized Chaplygin gas (GCG) model as a candidate of UDME is studied in this paper. By using the latest 162 ESSENCE type Ia supernovae (Sne Ia) data, 30 high red shift Sne Ia data and the distance ratio from z = 0.35 to z = 1089 (the red shift of decoupling), we obtain Ω _k = 0.076_-0.077^+0.093 and …

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…

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…

The Discovery of the Nearest Star

Glass, I. S.

In the 1830s, the double star α Centauri was the subject of the first successful stellar parallax measurement. For almost eighty years it remained the nearest star known. However, in 1915 at the Union Observatory in Johannesburg, R.T.A. Innes found a faint object near α Cen with a similar proper motion. Its parallax was measured over the following…

Turbulent and directed mass motions in various structures of the low corona

Delone, A. B.; Yakunina, G. V.; Porfir'eva, G. A. +1 more

[1] A brief review on turbulent and ordered plasma motions in the solar corona is presented. Velocities in quiet coronal regions, coronal loops, coronal holes, and cavities around quiescent prominences are analyzed. Data based on interferometric observations of several total solar eclipses obtained earlier by the authors and in addition the values…
