Observing the Solar Chromosphere
This review is split into two parts: one on chromospheric line formation in answer to the frequent question "where is my line formed", and one presenting state-of-the-art imagery of the chromosphere. In the first part I specifically treat the formation of the Na D lines, Ca II H & K, and Halpha.

What Happens in “Chromospheres”?
The recent paper by Santana et al. titled “Isolation, Characterization, and Differentiation of Progenitor Cells From Adult Human Adrenal Medulla” [1] is an interesting contribution to human chromaffin cell biology. However, I am concerned about omissions of important information in the literature that could lead to alternate interpretations of the ...

The Bright Rim Prominences according to 2.5D Radiative Transfer
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlying chromosphere. Despite several idealized models being proposed to explain

In this topical review I revisit the "chromospheric flare." This should currently be an outdated concept, because modern data seem to rule out the possiblity of a major flare happening independently in the chromosphere alone, but the chromosphere still plays a major observational role in many ways.

Magnetic Fields beneath Active Region Coronal Loops
We examine the hypothesis that multipolar magnetic fields advected by photospheric granules can contribute to heating the active chromosphere and corona.

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

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