Response of the outer cusp to the IMF rotation
Šimůnek, Jiří ; Šafránková, J. ; Němeček, Z.
The paper uses the INTERBALL-1 and MAGION=4 data to study the topology and dynamics of high-altitude cusp regions under changing solar wind conditions and interplanetary magnetic field (IMF) orientation. Preliminary analysis of the MAGION-4 ion energy spectra indicates the presence of the magnetosheath-like plasma well below the expected magnetopause position and a large region occupied by low-temperature dense plasma with the very low bulk velocity near the magnetopause.
