A little bit of background
Coronal rain is a common phenomenon occurring in active region coronal loops. As the name suggests, it shares many parallels with its terrestrial counterpart; it consists of cool plasma condensations falling from coronal heights towards the solar surface guided by magnetic field lines.… continue to the full article

Solar flares accelerate particles that then produce radio emission as they move through the corona. Type III radio bursts are commonly observed signatures of electron beams propagating along magnetic field that extends into interplanetary space.… continue to the full article

Observations of solar flare onsets show a rapid increase of hard and soft X-rays, ultra-violet emission with large Doppler blue-shifts associated with plasma upflows, and Hα emission with red-shifts up to 1–4 Å [1, 2, 3].… continue to the full article
