Dr Shahin Jafarzadeh (Queen's University Belfast, UK)02/06/2026, 11:00Science MeetingInvited
The seeing-free, multi-line, high-cadence observations delivered by Sunrise III provide a uniquely powerful new framework for studying waves and oscillations in the lower solar atmosphere. In this talk, I will present first results from our early-science investigations of active-region targets in the 327–329 nm near-UV window observed by SUSI, including line-dependent frequency structuring in...

We report high-spatial-resolution spectropolarimetric observations of a solar filament and its surrounding region, obtained with the Sunrise Chromospheric Infrared spectro-Polarimeter (SCIP) onboard the SUNRISE III balloon-borne observatory on 15 July 2024.

Ellerman bombs (EBs) are transient brightenings in the wings of chromospheric lines, recognized as signatures of magnetic reconnection in the lower solar atmosphere. However, the three-dimensional (3D) magnetic topology of EBs has remained elusive due to the lack of seamless height coverage in spectropolarimetric observations.
We present initial results from SUNRISE III/SCIP observations...

The weak-field approximation (WFA) is extensively used to infer solar magnetic fields due to its simplicity and low computational cost, often being applied beyond its formal range of validity. In this work, we reassess its limitations using Generalized Response Functions (GRFs), which quantify the sensitivity of WFA-derived magnetic fields to atmospheric parameters. We derive analytical...

Sunrise III/SCIP acquired a unique, high-precision spectropolarimetric dataset for a quiet Sun region near the disk center on 2024 July 11 with the full field of view of 58" x 58". With an integration time of 10 s per slit position, the scan was completed in 107 minutes without interruption, achieving a polarimetric precision of 0.03-0.04% (1$\sigma$). The multi-wavelength SCIP observations,...

The SCIP instrument on board Sunrise III observed the solar chromosphere at high spectral and spatial resolution through the Ca II 854.2 nm line. Kubo et al. (2026) present quiet Sun observations that reveal fine-structured network magnetic fields at chromospheric heights. By using the recently developed chromospheric extension of the MURaM code in combination with radiative transfer...
