LHR associated oblique noise bands
Chum, Jaroslav ; Jiříček, František ; Shklyar, D.
Observations onboard the Magion-5 satellite revealed oblique noise bands above the local Lower Hybrid Resonance (LHR) frequency - wave phenomena, which (to the best of authors' knowledge) have not been discussed yet. Examples of such oblique bands, both in review (large time-scale) spectrograms, and in detailed (small time-scale) spectrograms are presented. Based on ray-tracing simulations, an explanation of these oblique bands is suggested.
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.
