Tracing Ion-Scale Turbulence and Energy Cascade Rate from the Solar Corona to 1 au by E. P. Kontar et al.

January 20, 2026

The solar corona and solar wind are turbulent plasma environments where energy transfer from large-scale magnetohydrodynamic (MHD) fluctuations to smaller kinetic scales is thought to play a critical role in coronal heating and solar wind acceleration. Despite decades of research, the properties of turbulence at ion scales, where dissipation occurs, remain poorly constrained due to limited observational data. Moreover, the precise mechanisms that heat the corona, and accelerate and heat […]

Signatures of Confined and Eruptive Solar Flares in Microwave Spectra by E. W. Cliver et al.

January 6, 2026

Solar flares are generally divided into two classes: eruptive flares (with associated coronal mass ejections; CMEs, see previous CME nuggets by CESRA) and confined flares that lack CMEs. Because eruptive flares are the principal source of major space weather effects at Earth, relatively little attention was paid to confined flares until the great sunspot group of October 2014, designated NOAA 12192, passed across the solar disk giving rise to 35 […]
