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…

Active chromospheric fibril singularity: Coordinated observations from Solar Orbiter, SST, and IRIS

Reetika Joshi, Luc Rouppe van der Voort, Guillaume Aulanier +6

The fine structures of the solar chromosphere, driven by photospheric motions, play a crucial role in the dynamics of solar magnetic fields. Many have been already identified such…

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…
