Ensemble Modeling of Coronal Mass Ejection Arrival at 1 AU
Heliospheric imaging data can be used in ensemble modeling of CME arrival time at Earth to improve space weather forecasts, treating the solar wind as a 1-D incompressible hydrodynamic flow.
Power Outage When the Aurora Throws a Curve Ball
Omega-band aurora carries fast propagating electric currents in the azimuthal direction, producing geomagnetically induced currents that can cause power outage on the ground beneath.
Is Space Weather Worse by the Sea?
A new simulation of space-weather driven geoelectric fields at the land/sea conductivity boundary shows how these fields are magnified by both coastal effects and inhomogeneous land conductivity.
All Hands on Deck for Ionospheric Modeling
Challenges to studying the ionosphere’s ability to conduct electrical currents undercut scientists’ efforts to improve space weather forecasting models. Let’s tackle them together.
Space Traffic Management: Better Space Weather Forecasts Needed
Better forecasts of space-weather driven changes in thermospheric density are urgently needed to ensure safe management of the rapidly growing volume of space traffic in low Earth orbit.
“Electron Wings” Can Interfere with Spacecraft Measurements
Spacecraft sometimes produce a form of electrical self-interference as they zip through plasmas in space—a previously unreported effect that may be lurking in old data sets.
Atmospheric Drag Alters Satellite Orbits
A new modeling study shows how the density of the thermosphere influences the paths of satellites in low Earth orbit.
The Infrastructure Impacts of Solar Storms
A new book brings together insights from the space weather, geophysics, and power engineering communities to understand the characteristics and impacts of geomagnetically induced currents.
Space Weather Aviation Forecasting on a Global Scale
Under a new mandate, consortia of the world’s major space weather centers will disseminate new space-weather advisories for civil aviators representing a significant change-of-state for space weather.
