Spontaneous Hot Flow Anomalies in Earth's Foreshock
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract In recent years, we have learned that foreshock transients play an influential role in solar wind coupling with Earth's magnetosphere. These transients include spontaneous hot flow anomalies (SHFAs), which are characterized by dips in magnetic field magnitude and ion density, enhanced temperature, decelerated and deflected solar wind flow, and

The Correlation Function for Magnetic Field Fluctuations at Ion Dissipation Scales in the Solar Wind
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract This study investigates energy dissipation in small‐scale solar wind turbulence using a novel approach to autocorrelation function analysis leveraging high‐resolution data from the Magnetospheric Multiscale Mission (MMS). We analyze magnetic field fluctuations at ion dissipation scales, focusing on short 20‐s intervals to isolate dissipation ...

A correlative study of SSC's, interplanetary shocks, and solar activity [PDF]
A total of 93 SSC's were examined during the four year period from 1968 to 1971 at and near the peak of the solar activity cycle. Of the 93 SSC's 81 could be associated with solar activity, such as solar flares and radio bursts of Type II and Type IV ...

A Comparison of MAVEN SIR Observations With the Stationary WSA‐ENLIL Solar Wind Model
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract Predicting times of arrival and properties of space weather events, such as coronal mass ejections and stream interaction regions (SIRs), has become an important focus of the space physics community within recent years. Extensive efforts have been undertaken to model these space weather events throughout the heliosphere in order to better ...

Observation of discontinuities accompanied by interplanetary shock within the Martian magnetosheath
Astronomy & AstrophysicsAs fast forward interplanetary (IP) shocks travel outward in the IP medium, they might encounter planetary bow shocks (BSs) and then propagate into the magnetosheath. The interaction of an IP shock with a BS could create a new discontinuity, which has been predicted by theory and simulations, and commonly observed at Earth.

Interplanetary stream interfaces [PDF]
At l AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed.

Magnetic field of the magnetosheath [PDF]
The magnetic field of the magnetosheath is most naturally discussed in terms of its steady state and its fluctuating components. Theory of the steady state field is quite well developed and its essential features have been confirmed by observations.

Sudden commencement associated discontinuities in the interplanetary magnetic field observed by IMP 3 [PDF]
Solar Physics, 1969 The magnetic field measurements made by the magnetic field experiment on the IMP 3 (Explorer 28) spacecraft have been examined at the time of geomagnetic s.s.c. events. Thirty-six such events occurred while IMP 3 was in the interplanetary medium during 1965, 1966 and 1967 and have been analysed.
