GEOPHYSICS, ASTRONOMY, AND ASTROPHYSICS: ULF Waves Associated with Solar Wind Deceleration in the Earth's Foreshock

Dandouras, I.; Lucek, E.; Rème, H. +3 more

Characteristics of ULF waves associated with the solar wind deceleration in the Earth's foreshock on 6-7 April 2003 is studied using the wave telescope technique. In the satellite frame, the ULF waves are the left-handed polarized and quasi anti-parallel propagating mode, with a power peak at about 18.63 mHz. The wave vector in the GSE coordinates…

Properties of Field Aligned Current in Plasma Sheet Boundary Layers in Magnetotail: Cluster Observation

Dunlop, M.; Liu, Zhen-Xing; Shi, Jian-Kui +2 more

Field aligned current (FAC) distribution in the plasma sheet boundary layers (PSBLs) in the magnetotail is studied statistically by analysing magnetic field data from the Cluster 4-point measurements. The results show that the FAC distribution on the dusk side is not the same as that on the dawn side in the magnetotail. On the each side earthward …
