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…
Deep probing of the photospheric sunspot penumbra: no evidence for magnetic field-free gaps
J. M. Borrero, A. Asensio Ramos, M. Collados +24
Some models for the topology of the magnetic field in sunspot penumbrae predict the existence of field-free or dynamically weak-field regions in the deep Photosphere. To confirm or…
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…
Flows in and around active region NOAA12118 observed with the GREGOR solar telescope and SDO/HMI
M. Verma, C. Denker, H. Balthasar +28
Accurate measurements of magnetic and velocity fields in and around solar active regions are key to unlocking the mysteries of the formation and the decay of sunspots. High spatial…
