Wavelet analysis of ULF waves in the mercury's magnetosphere

, 2010
Ultra-low-frequency (ULF) waves have been observed in the Mercury's magnetosphere. In this work, Mariner-10 and MESSENGER high resolution magnetic field data are studied with wavelet analysis.

Ultra-relativistic electron flux enhancement under persistent high speed solar wind stream

Frontiers in Astronomy and Space Sciences
The physical mechanisms usually applied to explain the relativistic electron enhancement have been delved into to elucidate non-adiabatic electron acceleration resulting in the ultra-relativistic electron population observed in the outer radiation belt ...

Depression of the ULF geomagnetic pulsation related to ionospheric irregularities

Annals of Geophysics, 2004
We consider a depression in intensity of ULF magnetic pulsations, which is observed on the ground surface due to appearance of the irregularities in the ionosphere.

“Caterpillar” ULF Waves in the Dusk Side Sub‐Auroral Region: Conjugate Observations With SuperDARN, Arase and Ground Magnetometers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Effect of Field Line Torsion on the Polarization of ULF Waves

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract In this paper we suggest a simple modification of the dipole magnetic field which introduces field‐aligned currents and torsion to the field lines. The resulting field lines are not contained in the meridional planes and have resemblance to the geomagnetic field lines in the dawn and dusk flanks of the magnetosphere. We analyze polarization of

Statistical Study of Electric Pc5 Pulsations in the Inner Magnetosphere Observed by Cluster

Geophysical Research Letters
Ultra‐low frequency (ULF) waves in the Pc5 band are essential for the transport of electrons in the radiation belt and the transport of energy from the solar wind into the magnetosphere.

Solar cycle evolution of ULF wave power in solar wind and on ground

Journal of Space Weather and Space Climate, 2020
The solar cycle evolution of the ultra-low frequency (ULF) power was studied in solar wind and on ground. We aim finding out how the ULF power in interplanetary and on ground magnetic field evolves over the solar cycle 23 (SC23) and how well do they ...

Disclosing the May 2024 Geomagnetic Storm: A Synergistic View From the Remote Talos Dome Station on the Antarctic Plateau, Ground Networks, and Space

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We analyze the May 2024 geomagnetic storm using a unique longitudinal chain of Antarctic stations, including the new remote Talos Dome measurement site. By combining its high‐resolution magnetic data with observed values from coastal (Terra Nova Bay and Scott Base) and the polar‐cap (Dome C) observatories, Southern Hemisphere auroral indices ...

ULF waves in Ganymede's upstream magnetosphere [PDF]

, 2013
Ganymede's mini-magnetosphere, embedded in Jupiter's larger one, sustains ULF (ultra-low frequency) waves that are analyzed here using data from two Galileo flybys that penetrate deeply into the upstream closed field line region. The magnetometer data
