Abstract

The article focuses on the investigation of coronal rain—cool, dense plasma condensations—in the solar corona and its role in the mass and energy cycle of solar flares. Using high-resolution observations from the Interface Region Imaging Spectrograph (IRIS) and the Atmospheric Imaging Assembly on the Solar Dynamics Observatory (AIA/SDO), the study compares quiescent and flare-driven coronal rain during different flare phases. Findings reveal that coronal rain increases significantly during the gradual phase of a C2.1-class flare, with downward velocities averaging 36–50 km/s and morphological changes primarily in rain length rather than width. The research highlights coronal rain as a key component in returning mass and energy from the corona to the chromosphere, following chromospheric evaporation during the flare’s impulsive phase.
