Estimation of Reconnection Rate From Soft X‐Ray Emission at the Earth's Dayside Magnetopause

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract We propose an approach to estimating the reconnection rate by utilizing soft X‐rays emitted during the solar wind charge exchange (SWCX) process at the Earth's magnetopause. Employing a high‐resolution global magnetohydrodynamic (MHD) simulation model of the magnetosphere, we investigated the SWCX emission around the magnetopause during a ...

Uncovering the heterogeneity of a solar flare mechanism with mixture models

open access: yesFrontiers in Astronomy and Space Sciences
The physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...

The 1859 space weather event revisited: limits of extreme activity

open access: yesJournal of Space Weather and Space Climate, 2013
The solar flare on 1 September 1859 and its associated geomagnetic storm remain the standard for an extreme solar-terrestrial event. The most recent estimates of the flare soft X-ray (SXR) peak intensity and Dst magnetic storm index for this event are ...
