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…

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…

TuMag: the tunable magnetograph for the Sunrise III mission

J. C. del Toro Iniesta, D. Orozco Suárez, A. Álvarez-Herrero +61

One of the instruments aboard the Sunrise III mission, the Tunable Magnetograph (TuMag), is a tunable imaging spectropolarimeter in visible wavelengths. It is designed to probe the…

The connection between internetwork magnetic elements and supergranular flows

D. Orozco Suárez, L. R. Bellot Rubio, Y. Katsukawa

The advection of internetwork magnetic elements by supergranular convective flows is investigated using high spatial resolution, high cadence, and high signal-to-noise ratio Na I D…

Reconstruction of total solar irradiance variability as simultaneously apparent from Solar Orbiter and Solar Dynamics Observatory

K. L. Yeo, N. A. Krivova, S. K. Solanki +42

Solar irradiance variability has been monitored almost exclusively from the Earth's perspective. {We present a method to combine the unprecedented observations of the photospheric…

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.…
