Relationship of Transport Coefficients with Statistical Quantities of Charged Particles
The Astrophysical Journal, 2023 In previous studies, a general spatial transport equation was derived from the Fokker–Planck equation. The latter equation contains an infinite number of spatial derivative terms T _n = κ _nz ∂ ^n F /∂ z ^n with n = 1, 2, 3, ⋯ .

Energetics of Shock-triggered Supersubstorms (SML < −2500 nT)
The Astrophysical Journal, 2023 The solar wind energy input and dissipation in the magnetospheric–ionospheric systems of 17 supersubstorms (SSSs: SML < −2500 nT) triggered by interplanetary shocks during solar cycles 23 and 24 are studied in detail. The SSS events had durations ranging

Are Switchback Boundaries Observed by Parker Solar Probe Closed?
The Astrophysical Journal, 2023 Switchbacks are sudden and large deflections in the magnetic field that Parker Solar Probe frequently observes in the inner heliosphere. Their ubiquitous occurrence has prompted numerous studies to determine their nature and origin.

Does Magnetic Reconnection Occur in the Near Lunar Surface Environment?
Geophysical Research Letters, 2023 The near lunar surface contains small‐scale magnetic field structures that provide a natural test bed for observing plasmas with a non‐zero Hall electric field, as well as potentially facilitating electron‐only reconnection.

Case studies of space weather events from their launching on the Sun to their impacts on power systems on the Earth [PDF]
Annales Geophysicae, 2002 Active geomagnetic conditions on 12–13, 15–16, and 22–23 September 1999 resulted in geomagnetically induced currents (GIC) measurable in power systems in Canada and the United States.

Occurrence and Evolution of Switchbacks in the Inner Heliosphere: Parker Solar Probe Observations
The Astrophysical Journal Letters, 2023 Since its launch in 2018, the Parker Solar Probe (PSP) mission revealed the presence of numerous fascinating phenomena occurring closer to the Sun, such as the presence of ubiquitous switchbacks (SBs).
