Magnetic properties of Active Region NOAA 13079 from photosphere to the chromosphere

ABSTRAKT / ABSTRACT :

Spectro-polarimetric measurements of Active Region NOAA 13079 obtained on August 13,
2022 with the GREGOR Infrared Spectrograph (GRIS) in the Ca I 10838 Å, Si I 10828 Å,
and He I 10830 Å spectral lines, combined with observations from the High-resolution
Fast Imager (HIFI), are analysed. The study focuses on the magnetic properties of
the solar atmosphere above a sunspot at different atmospheric heights.

The magnetic field vector is inferred from full-Stokes profiles using a
spectral-line inversion technique. This approach enables the investigation of both
magnetic and dynamic properties across different atmospheric heights. The results
provide insight into the structure and behaviour of the solar atmosphere above the
sunspot.
