Recent advances in the understanding of the Wilson depression in Sunspots more

The solar chromosphere harbours small dynamic events which are associated with its heating. Our observations high resolution observations give a hint at a unified picture of magnetic heating in the solar atmosphere more

Advances in the autonomous on-board data processing system for SO/PHI instrument to overcome the very low amount of telemetry available for Solar Orbiter more

A new attempt to prove the new capabilities of GRIS+ instrument at the GREGOR observatory (Spain) is about to start more

Diffraction-limitedobservations in the near-infrared spectral region more

In a technical campaign in October 2017 a new, hi-speed infrared camera was installed at the GREGOR telescope. The new camera will allow for highly accurate magnetic field measurements in the solar photosphere and chromosphere at the highest spatial resolution achievable with GREGOR. more

2nd GREGOR Science Meeting

November 08, 2016

Scientists from the GREGOR partner institutes in Germany and Spain met for the second time at MPS to discuss the latest results obtained with the 1.5m GREGOR ground-based solar telescope. more

The recently developed prototype of the Fast Solar Polarimeter (FSP) acquired high-resolution, high-cadence polarimetric measurements of a pore showing the potential of the instrument to detect fast-evolving, small-scale solar features. more

Scientists from Germany, Spain and the Czech Republic met in January 2016 to present and discuss the scientific outcome of the observing season 2015. A wealth of high-quality data sets were presented, covering many facets of the solar atmosphere: from quiet regions to sunspots, from the deep photosphere up to chromospheric heights. The research presented during this meeting will soon be published in a special issue of Astronomy & Astrophysics. more

A novel inversion technique developed at MPS allowed to investigate the 3-dimensional structure of a sunspot in the photosphere of the Sun. The physical conditions (temperature, flow velocities, magnetic fields) were analyzed in unprecedented resolution using data from the spectropolarimeter onboard the Japanese Hinode spacecraft. A striking similarity between the sunspot umbra and the dark lanes (spines) of the penumbra could be identified. more
