3D MHD Simulations of Coronal Loops Heated via Magnetic Braiding. II. Automatic Detection of Reconnection Outflows and Statistical Analysis of Their Properties

The Astrophysical Journal
Recent observations of fast and bursty “nanojets” suggest novel diagnostics of nanoflare heating in the solar corona. The aim of this work is to investigate the presence and properties of reconnection outflows, similar to observed nanojets, in numerical ...

Simultaneous TRACERS and THEMIS Observations of Reversed Cusp Ion Dispersions and Dual‐Lobe Reconnection

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present observations from two consecutive TRACERS‐2 orbits through the northern low‐altitude cusp. During the first crossing, TRACERS‐2 observed reversed cusp ion dispersion and sunward convection, consistent with magnetopause reconnection tailward of the cusp during this northward IMF interval.

Unraveling the Fine‐Scale Tapestry of Solar Wind at 1AU

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Solar wind is a complex network of distinct magnetic flux tubes, each contained and separated by a current sheet. In this study, more than 50,000 current sheets in the solar wind are identified and characterized for the first time, using multi‐point Cluster observations during solar minimum and maximum intervals.

MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

Direct Observations of Magnetic Reconnections at the Magnetopause of the Martian Mini‐Magnetosphere

Geophysical Research Letters
While Mars lacks a global intrinsic magnetic field, it does exhibit crustal magnetic anomalies (mostly in its Southern Hemisphere). These crustal magnetic anomalies directly interact with solar wind, which forms a mini‐magnetosphere and a region denoted ...

Connecting Solar Wind Velocity Spikes Measured by Solar Orbiter and Coronal Brightenings Observed by SDO

The Astrophysical Journal Letters
The Parker Solar Probe's discovery that magnetic switchbacks and velocity spikes in the young solar wind are abundant has prompted intensive research into their origin(s) and formation mechanism(s) in the solar atmosphere.
