Description
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 computations we were able to find similar fine-structured network magnetic fields in an enhanced network simulation. In the model atmosphere, opposite magnetic field polarities can be found as elongated structures close to the otherwise expanding main network polarity. At these locations, the magnetic field is twisted in the simulation, similar to twisted flux ropes. In this work we present the comparison between the observation and simulation and the evolution of such “opposite-polarity-intrusions”. We additionally provide possible future topics for interpreting Sunrise III data with the help of forward-modeled synthetic spectra.
