Observations of a new foreshock region upstream of a foreshock bubble's shock [PDF]

Geophysical Research Letters, 2016
Earth's foreshock is a region within the solar wind upstream of Earth's bow shock filled with backstreaming solar wind particles reflected at the shock.

Statistical Evaluation of a Foreshock Transient Model Using Ground‐Based ULF Wave Observations

Geophysical Research Letters
Hot flow anomalies and foreshock bubbles are discontinuity–driven foreshock transients that generate significant geospace disturbances. A recently developed analytical model can predict their upstream perturbations.

Simultaneous observations of MHD hot flow anomaly and kinetic foreshock bubble and their impacts

Frontiers in Physics
Hot flow anomalies (HFAs) and foreshock bubbles (FBs) are two types of transient phenomena characterized by flow deflected and hot cores bounded by one or two compressional boundaries in the foreshock.

Transient Foreshock Structures Upstream of Mars: Implications of the Small Martian Bow Shock [PDF]

Geophysical Research Letters, 2023
The typical subsolar stand‐off distance of Mars' bow shock is of the order of a solar wind ion convective gyroradius, making it highly non‐planar to incident ions.

Cluster observations of foreshock bubbles and their boundary shocks

Earth, Planets and Space
Foreshock Bubbles (FBs) are transient structures in the Earth’s foreshock region, which are diamagnetic cavities formed by hot ion concentration around interplanetary magnetic field discontinuities and have significant compressional boundary shocks ...

Transient upstream mesoscale structures: drivers of solar-quiet space weather

Frontiers in Astronomy and Space Sciences
In recent years, it has become increasingly clear that space weather disturbances can be triggered by transient upstream mesoscale structures (TUMS), independently of the occurrence of large-scale solar wind (SW) structures, such as interplanetary ...

Clustering of Global Magnetospheric Observations

Journal of Geophysical Research: Machine Learning and Computation
The use of supervised methods in space science have demonstrated powerful capability in classification tasks, but purely unsupervised methods have been less utilized for the classification of spacecraft observations.
