Sunrise III: Instrument, mission, data, and first results

Sami K. Solanki, H. N. Smitha, Andreas Lagg +66

Sunrise III is a stratospheric balloon-borne solar observatory with a 1-m diameter telescope and three post-focus instruments, along with an image stabilisation system, all within…

Coronal voids and their magnetic nature

J. D. Nölke, S. K. Solanki, J. Hirzberger +68

Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these…

Stereoscopic disambiguation of vector magnetograms: first applications to SO/PHI-HRT data

G. Valori, D. Calchetti, A. Moreno Vacas +34

Spectropolarimetric reconstructions of the photospheric vector magnetic field are intrinsically limited by the 180-ambiguity in the orientation of the transverse component.…

Wavefront error of PHI/HRT on Solar Orbiter at various heliocentric distances

F. Kahil, A. Gandorfer, J. Hirzberger +31

We use wavefront sensing to characterise the image quality of the the High Resolution Telescope (HRT) of the Polarimetric and Helioseismic Imager (SO/PHI) data products during the…

Direct assessment of SDO/HMI helioseismology of active regions on the Sun's far side using SO/PHI magnetograms

D. Yang, L. Gizon, H. Barucq +47

Earth-side observations of solar p modes can be used to image and monitor magnetic activity on the Sun's far side. Here we use magnetograms of the far side obtained by the Polarime…

Spectropolarimetric investigation of magnetohydrodynamic wave modes in the photosphere: First results from PHI on board Solar Orbiter

D. Calchetti, M. Stangalini, S. Jafarzadeh +31

In November 2021, Solar Orbiter started its nominal mission phase. The remote-sensing instruments on board the spacecraft acquired scientific data during three observing windows su…
