The first out-of-ecliptic observations of the polar magnetic field of the Sun
D. Calchetti, S. K. Solanki, J. Hirzberger +25
Direct remote-sensing observations of the solar poles have been hindered by the restricted view obtained from the ecliptic plane. For the first time ever, Solar Orbiter with its re…
Solar limb faculae: intensity contrast from two vantage points
K. Albert, J. Hirzberger, N. A. Krivova +9
Small-scale magnetic flux concentrations contribute significantly to the brightness variations of the Sun, yet observing them - particularly their magnetic field - near the solar l…
Solar photospheric velocities measured in space: a comparison between SO/PHI-HRT and SDO/HMI
D. Calchetti, K. Albert, F. J. Bailén +15
The Polarimetric and Helioseismic Imager (SO/PHI) onboard Solar Orbiter is a spectropolarimeter scanning the Fe I line at 617.3 nm, providing data of the solar photosphere. The sam…
3D structures of the base of small-scale recurrent jets revealed by Solar orbiter
Xiaohong Li, Sami K. Solanki, Thomas Wiegelmann +7
Solar jets, characterized by small-scale plasma ejections along open magnetic field lines or the legs of large-scale coronal loops, play a crucial role in the dynamics of the solar…
Solar Orbiter reveals persistent magnetic reconnection in medium-scale filament eruptions
Song Tan, Alexander Warmuth, Frédéric Schuller +7
Solar filament eruptions play a key role in driving space weather, yet their fine-scale evolution remains poorly understood due to observational limitations. Using unprecedented hi…
Supergranulation and Poleward Migration of the Magnetic Field at High Latitudes of the Sun
L. P. Chitta, D. Calchetti, J. Hirzberger +26
Magnetoconvection at the solar surface governs the dynamics in the upper solar atmosphere and sustains the heliosphere. Properties of this fundamental process are poorly described…
A magnetic avalanche as the central engine powering a solar flare
L. P. Chitta, D. I. Pontin, E. R. Priest +17
Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelera…
Sunrise III: Overview of Observatory and Instruments
Andreas Korpi-Lagg, Achim Gandorfer, Sami K. Solanki +117
In July 2024, Sunrise completed its third successful science flight. The Sunrise III observatory had been upgraded significantly after the two previous successful flights in 2009 a…
