The role of the chromospheric magnetic canopy in the formation of a sunspot penumbra
P. Lindner, C. Kuckein, S. J. González Manrique +3
While it is being conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the connectivity between the p…
GREGOR: Optics Redesign and Updates from 2018-2020
Lucia Kleint, Thomas Berkefeld, Miguel Esteves +6
The GREGOR telescope was inaugurated in 2012. In 2018, we started a complete upgrade, involving optics, alignment, instrumentation, mechanical upgrades for vibration reduction, upd…
The Polarimetric and Helioseismic Imager on Solar Orbiter
S. K. Solanki, J. C. del Toro Iniesta, J. Woch +121
This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from o…
Photospheric Magnetic Fields of the Trailing Sunspots in Active Region NOAA 12396
M. Verma, H. Balthasar, C. Denker +27
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…
Spatial variations of the Sr i 4607 Å scattering polarization peak
M. Bianda, S. Berdyugina, D. Gisler +5
Context. The scattering polarization signal observed in the photospheric Sr i 4607 Å line is expected to vary at granular spatial scales. This variation can be due to changes in th…
Three-dimensional structure of a sunspot light bridge
T. Felipe, M. Collados, E. Khomenko +26
Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar physics. Light bridges are commonl…
