Abstract
The Dynamics of Solar-Stellar Atmospheres: Winds, Flares and CMEs
Spectroscopic inversion of the Ca ii 8542 Å line in an C-class solar flare
Queen's University Belfast
We study a C8.4 class solar flare SOL2016-05-14T11:34 UT using high-resolution spectral imaging in the Ca ii 8542 Å line obtained with the CRISP imaging spectropolarimeter on the Swedish 1-m Solar Telescope. Spectroscopic inversions of the Ca ii 8542 Å line using the non-LTE code NICOLE are used to investigate the evolution of the temperature and velocity structure in the flare chromosphere. A comparison of the temperature stratification in flaring and non-flaring areas show strong footpoint heating during the flare peak in the lower atmosphere. The temperature stratification of the non-flaring areas is unchanged.
