Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

Evolution of the interplanetary magnetic field [PDF]
, 1994 Remote observations of magnetic field topologies in the solar corona and in situ observations of the solar wind and interplanetary magnetic field (IMF) in interplanetary space are used to examine the temporal evolution of the spatial distribution of open and closed field regions emanating from the Sun.

BepiColombo at Mercury: Three Flybys, Three Magnetospheres
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.

Scale and Time Dependence of Alfvénicity in the Solar Wind as Observed by the Parker Solar Probe
The Astrophysical JournalAlfvénicity is a well-known property, common in the solar wind, characterized by a high correlation between magnetic and velocity fluctuations. Data from the Parker Solar Probe (PSP) enable the study of this property closer to the Sun than ever before ...

Evolutionary Dynamics of Counterhelical Magnetic Flux Ropes
The Astrophysical JournalUpon interaction, a pair of magnetic flux ropes can merge to form a new pair, each consisting of opposite helicity along their axis. Magnetic helicity along such new structures may annihilate and release the energy of the azimuthal magnetic field.

Interplanetary magnetic fields, their fluctuations, and cosmic ray variations [PDF]
The cause of Forbush decreases is examined using neutron monitor data and measurements of the interplanetary magnetic field. It is found that for the period examined (Dec.

The Astrophysical JournalThe gradient and curvature of the Parker spiral interplanetary magnetic field give rise to curvature and gradient guiding-center drifts on cosmic rays (CRs). The plasma turbulence present in interplanetary space is thought to suppress the drifts; however,
