Omega Bands as a Source of Large dB/dt in the Dawn Sector

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Omega band activity has the potential to cause geomagnetically induced currents as they can cause large values of dB/dt $\mathrm{d}B/\mathrm{d}t$. We have undertaken a multi‐instrument study of an omega event which occurred from 13 to 14 November 2012, during a period of southward IMF. Measurements from the European Incoherent SCATter (EISCAT)

Spatial Variability and Correlation Lengths Within Stream Interaction Regions at 1 au: Comparison Between ACE and Wind

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Understanding the spatial variability and correlation lengths throughout Stream Interaction Regions (SIRs) has importance both for fundamentally understanding the structuring of the solar wind and SIRs and for space weather operations. SIR observations from Advanced Composition Explorer and Wind are utilized to characterize the spatial ...

APXS Derived Geochemistry of Shallow Water Lens Bodies Within the Mirador Formation, Gale Crater, Mars—Evidence for Intermittent Wet Periods and Implications for the Water Record

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mount Sharp group in Gale crater is typically interpreted to record a progressive change (with increasing elevation) from wetter fluvio‐lacustrine environments to dry, eolian environments. This shift has been linked to orbital evidence for a global change in environmental and depositional conditions leading to an overall drying out of Mars.

Effects of Mineralogy and UV Radiation on the Detectability of Amino Acids Within the Martian Regolith: The Case for a Combined Chromatographical and Spectroscopical Approach

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Amino acids are an extremely heterogeneous group of biomolecules essential for life on Earth. Their biosignatures are expected to be easily degraded on the Martian surface as the absence of a thick atmosphere and a magnetosphere leads to most of the solar radiation directly reaching its surface.

Inter‐Solar‐Cycle Variability of Extreme Geomagnetic Storms

Space Weather, Volume 23, Issue 11, November 2025.
Abstract The occurrence of extreme space weather events, and, in particular, severe geomagnetic storms, while rare, can result in disproportionately large societal consequences. Accurate estimates of their likelihood over the timescale of a solar cycle or longer can provide crucial and actionable information for policymakers.

Ion Composition and Electron Pitch Angle Variations for Interchange Events in Jupiter's Inner Magnetosphere

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported around Jupiter and Saturn.
