Sources of the cusp plasma for the different sign of IMF By
Šimůnek, Jiří ; Šafránková, J. ; Němeček, Z. ; Wing, S.
The importance of the interplanetary magnetic field (IMF) direction for the cusp formation was dicovered a long time ago. A sign of the IMF Bz component is believed to be responsible for a location of the plasma entry into the cusp. The paper uses the INTERBALL-1 and MAGION-4 data to study the high-altitude cusp topology for different IMF By orientations. The study reveals the importance of IMF horizontal components on the cusp configuration as well as on small-scale processes at the outer cusp. We discuss an influence of the tilt angle of the Earth's dipole on these processes.

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.
