Linking long-term switchback variability at 1 au to solar-surface mechanisms: A 27-year statistical study

Astronomy & Astrophysics
Context. Switchbacks–transient, large-angle deflections of the interplanetary magnetic field–pervade the solar wind, yet their origin remains disputed. Current ex situ theories, notably coronal jets and interchange reconnection, are typically tested on ...

Observation of Shortwave Fadeout Events Using Chinese Dual Auroral Radar Network (CN‐DARN) During the Severe Solar Storm in May 2024

Space Weather
Shortwave fadeout (SWF) is a typical dayside high‐frequency radio disturbance caused by solar flare‐induced ionospheric ionization enhancement. Using newly built Chinese Dual Auroral Radar Network (CN‐DARN) observations, we investigate two X‐flare‐driven

Optimizing calibration of fluxgate magnetometer offsets using magnetic holes in the earth’s magnetosheath

Earth, Planets and Space
The offset of the fluxgate magnetometer (FGM) drifts slowly with time and temperature, requiring regular in-flight calibration. Recent studies utilizing magnetic holes have optimized calibration error to ~ 0.3 nT in the solar wind, but an order larger in
