ULF Waves Observed by Lunar Prospector

Journal of Geophysical Research: Space Physics, 2021
AbstractWe have studied the spatial distribution of ultra‐low frequency (ULF) in the vicinity of the Moon using Lunar Prospector (LP) magnetometer data obtained at ∼100 km altitude during the period from February 20, 1998 to November 30, 1998. The lunar ULF waves are mostly identified over a broad frequency range of 10–60 mHz in the spacecraft frame ...

Ionospheric Feedback and ULF Quarter‐Waves

Journal of Geophysical Research: Space Physics, 2022
AbstractThis paper presents results from the numerical investigation of nonlinear feedback interactions between ULF field‐aligned currents (FACs) and the ionospheric plasma in the global magnetospheric resonator with a non‐symmetrical distribution of the plasma density in the conjugate hemispheres.

ULF Waves: Conjugated Ground-Satellite Relationships

Space Science Reviews, 1978
We study the simultaneous occurrence of ULF waves observed on board GEOS and at two of its ‘conjugated’ stations: Husafell (Iceland) and Skibotn (Norway). We try to deduce some properties of the regions in which these waves are generated. The few number of simultaneous observations of ‘pearl’ events indicates that such structured oscillations can occur

A study of ULF wave foreshock morphology—II: spatial variation of ULF waves

Planetary and Space Science, 1992
Abstract Two case studies are used to show the evolution of upstream ULF waves in the Earth's foreshock region. During these two intervals the IMF cone angle was nearly constant over an extended time period and the ISEE spacecraft was in the foreshock region and traveled a large distance through it.

ULF waves in the foreshock

Advances in Space Research, 1995
Plasma waves observed in the VLF range upstream of planetary bow shocks not only modify the particle distributions, but also provide important information about the acceleration processes that occur at the bow shock. Electron plasma oscillations observed near the tangent field line in the electron foreshock are generated by electrons reflected at the ...
