40. Multi-line Diagnostic of Very Quiet Sun Brightening Events Detected by SUNRISE III/SUSI

Science Meeting

We describe transient brightenings in a very quiet Sun region detected with SUNRISE III/SUSI spectroscopic observations covering the Ca II K at 3933.663 Angstrom. The Ca II K line is one of the strongest lines in the solar spectrum and serves as a key diagnostic of the solar atmosphere. On its wings there are plenty of absorption lines that originate from various atmospheric heights. At some...

7. 3D modeling of Ca II emission above the limb

Ivan Milic (KIS)

Science Meeting

Sunrise III identified extended Ca II K emission above the limb. In a recently submitted letter, we described this emission and performed a simple radiative transfer modeling to compare emission properties with 1D and 3D models of the solar atmosphere. Here, we present more detailed modeling, including the 3D scattering in the upper chromosphere, as well as the discussion on the intensity of...

8. Characterization of a solar pore from photosphere to chromosphere with SCIP@Sunrise

Ana Belen Grinon-Marin (Institute for Solar Physics / Stockholm University)

02/06/2026, 14:45

Science Meeting

In this talk we aim at deepening our understanding of pores with particular focus on their characterization at middle atmospheric layers (upper photosphere / lower chromosphere). Pores are small and dark magnetic features observed in the photosphere that are composed of only an umbral core, i.e. they do not have penumbral structure, and have short lifetimes compared to larger sunspots. The...

20. Magnetic Connectivity and Chromospheric Acceleration in an Arch Filament System Observed with Sunrise III

Sergio Javier González Manrique (Instituto de Astrofisica de Canarias)

02/06/2026, 15:00

Science Meeting

Emerging flux regions (EFRs) are highly dynamic environments where magnetic fields rise through the solar atmosphere, often giving rise to arch filament systems (AFSs) and filamentary structures. We present high-resolution, multi-line observations of an EFR obtained during the Sunrise III mission, combining spectropolarimetric measurements from TuMag and SCIP with EUV observations from SDO....

41. Light in the darkness: uncovering hidden features near the solar limb using Sunrise III/SUSI

Juan Sebastian Castellanos Duran (MPS)

02/06/2026, 15:15

Science Meeting

Sunrise III/SUSI conducted observations at the 409 nm spectral window, capturing an exceptional scan from near the disk up to 7 Mm above it. Ground-based acquisition of such data is hindered by foreshortening, low contrast, and variable atmospheric conditions. Over one hundred spectral transitions were detected, including Hydrogen (H$\delta$), Sr II, rare-earth elements such as La, Dy, and Hf,...
