Determining the Magnetic Field of Active Region Plages Using the Whole CLASP2/2.1 Spectral Window

The Astrophysical Journal
The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the magnetism of the solar chromosphere.

Solar Flare Ribbon Fronts. II. Evolution of Heating Rates in Individual Flare Footpoints

The Astrophysical Journal
Solar flare ribbon fronts appear ahead of the bright structures that normally characterize solar flares, and can persist for an extended period of time in spatially localized patches before transitioning to “regular” bright ribbons. They likely represent

Solar Chromospheric Heating by Magnetohydrodynamic Waves: Dependence on the Inclination of the Magnetic Field

The Astrophysical Journal
A proposed mechanism for solar chromospheric heating is magnetohydrodynamic waves propagating upward along magnetic field lines and dissipating their energy in the chromosphere.
