Abstract. IMP 6 observations of the plasma boundary layer (PBL) and magnetopause layer (MPL) of the earth's magnetosphere indicate that plasma in the low-latitude portion of the PBL is supplied primarily by direct transport of magnetosheath plasma across the MPL and that this transport process is relatively widespread over the entire sunward magnetospheric boundary.

A magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. It is created by a star or planet with an active interior dynamo. In the space environment close to a planetary body, the magnetic field resembles a magnetic r out, field lines can be significantly distorted by the flow of.

At very great distances (some to R e downstream from the earth) the dawn and dusk boundary layers become joined together, and the magnetotail is essentially just boundary layer plasma, on closed magnetic field lines.

Evidence concerning closed field lines in the polar cap is the migration of breakup auroras near midnight during the Cited by: Abstract. The magnetopause and the magnetospheric boundary layer constitute the interface between the shocked solar wind plasma and the terrestrial magnetic cavity populated by a predominantly hot plasma in the outer portion and a cold (ionospheric) plasma near the by: Get this from a library.

The interaction of the solar wind with the magnetosphere is examined from the standpoint of fundamental processes in physics and, whenever possible, observational data.
