“…Looking at a boundary such as the magnetopause with one spacecraft gives a rather simple image. Later on, by using two spacecraft missions such as ISEE 1 and 2 (Berchem and Russell, 1982) and INTERBALL-1/MAGION4 (Safrankova et al, 1997) a moving and oscillating layer was detected. Using now the Cluster "microscope" clearly increases the complexity of the interpretation.…”

Abstract. We present the study of one of the first magnetopause crossings observed by the four Cluster spacecraft simultaneously, on 10 December 2000. Although the delays between the crossings are very short, the features of the boundary appear quite different as seen by the different spacecraft, strongly suggesting the presence of a local curvature of the magnetopause at that time. The small-scale fluctuations observed by the STAFF search-coil experiment are placed in relation to this context. A preliminary investigation of their behaviour on the boundary and in the neighbourhood magnetosheath is performed in comparison with the theoretical model of Belmont and Rezeau (2001), which describes the interaction of waves with the boundary.

“…The early Explorer 12 observations [Sonnerup and Cahill, 1968] were in agreement with the wide RD analysis. Berchem and Russell [1982b], however, failed to find the predicted relationship using ISEE 1 and 2 data. They conclude that the observed rotation sense is not consistent with the electron whistler polarization theory.…”

Abstract. De Keyser and Roth recently have developed a kinetic model of the tangential discontinuity magnetopause. This model predicts (1) that not all configurations of magnetic field vectors and magnetosheath velocity allow an equilibrium to exist and (2) that there is a preference for a particular magnetic field rotation sense across the magnetopause due to the different response of ions and electrons to the electric field in the current layer. In the present paper we extend the original model to allow for different magnetospheric and magnetosheath densities and temperatures, and we show that the conclusions remain essentially unchanged. Given the large-scale magnetosheath flow pattern around the magnetosphere, we also compute which regions of the dayside magnetopause may be in tangential discontinuity equilibrium for a given magnetosheath field orientation.

“…For the case of the earth's magnetosphere, it is found through many observations (RUSSELL and ELPHIC,1978;RUSSELL and GREENSTADT,1979;PASCHMANN et al, 1978;PARKS et al, 1978;EASTMAN and HONES, 1979;BERCHEN and RUSSELL, 1982;etc.) that the bow shock, the magnetosheath, the magnetopause, the boundary layer and the magnetosphere mantle are existing. Due to limitation of the data, however, we could not definitely conclude the characteristics for these transient regions such as regions II and IV, whether the regions are similar to the earth's magnetosphericc boundary layer or not.…”

A structure of the Jovian magnetospheric boundary region near the equatorial plane which is produced by the interaction between the solar wind plasma and the internal planetary wind plasma in the magnetodisc , has been studied. A possibility of the existence of the internal shock, as a innermost boundary between the planetary wind and the region of the intrinsic magnetic field, has been investigated theoretically using two dimensional Rankine-Hugoniot relation in MHD regime. The results of present numerical calculation for the internal shock indicate the asymmetrical characteristics; that is, the internal shock is strong in the dawn side of the Jovian magnetodisc, while the shock formed in the dusk side is weak and disappears at the intermediate position reflecting the azimuthally flowing nature of the Jovian disc wind.A unique model of the Jovian low latitude magnetospheric boundary structure which consists of the double shock (bow shock and internal shock) and the double magnetopause (magnetopause and internal magnetopause), has been proposed . The data obtained by the in-situ observations suggest the existence of the theoretically proposed boundary structure. This coincidence suggests a indirect confirmation of the existence of the Jovian disc wind which is proposed on the theoretical base ,
