Inference of magnetic fields in the very quiet Sun
M. J. Mart\' inez González, A. Pastor Yabar, A. Lagg +29
We present high-precision spectro-polarimetric data with high spatial resolution (0.4) of the very quiet Sun at 1.56m obtained with the GREGOR telescope to shed some light o…
Active region fine structure observed at 0.08 arcsec resolution
R. Schlichenmaier, O. von der Lühe, S. Hoch +19
The various mechanisms of magneto-convective energy transport determines the structure of sunspots and active regions. We characterise the appearance of light bridges and other fin…
Magnetic fields of opposite polarity in sunspot penumbrae
M. Franz, M. Collados, C. Bethge +25
Context. A significant part of the penumbral magnetic field returns below the surface in the very deep photosphere. For lines in the visible, a large portion of this return field c…
Horizontal flow fields in and around a small active region-- The transition period between flux emergence and decay
M. Verma, C. Denker, H. Balthasar +28
Aims. Combining high-resolution and synoptic observations aims to provide a comprehensive description of flux emergence at photospheric level and of the growth process that eventua…
Slipping reconnection in a solar flare observed in high resolution with the GREGOR solar telescope
M. Sobotka, J. Dudík, C. Denker +23
A small flare ribbon above a sunspot umbra in active region 12205 was observed on November 7, 2014, at 12:00 UT in the blue imaging channel of the 1.5 m GREGOR telescope, using a 1…
Probing deep photospheric layers of the quiet Sun with high magnetic sensitivity
A. Lagg, S. K. Solanki, H. -P. Doerr +31
Context. Investigations of the magnetism of the quiet Sun are hindered by extremely weak polarization signals in Fraunhofer spectral lines. Photon noise, straylight, and the system…
