| Abstract: |
The solar magnetic field is responsible for all aspects of solar activity.
Sunspots are the main manifestation of the ensuing solar activity. Combining
high-resolution and synoptic observations has the ambition to provide a
comprehensive description of the sunspot growth and decay processes. Active
region NOAA 12396 emerged on 2015 August 3 and was observed three days later
with the 1.5-meter GREGOR solar telescope on 2015 August 6. High-resolution
spectropolarimetric data from the GREGOR Infrared Spectrograph (GRIS) are
obtained in the photospheric lines Si I λ1082.7 nm and
Ca I λ1083.9 nm, together with the chromospheric
He I λ1083.0 nm triplet. These near-infrared
spectropolarimetric observations were complemented by synoptic line-of-sight
magnetograms and continuum images of the Helioseismic and Magnetic Imager (HMI)
and EUV images of the Atmospheric Imaging Assembly (AIA) on board the Solar
Dynamics Observatory (SDO). |
