A forest of emission lines observed by Sunrise III/SUSI above the solar limb
J. S. Castellanos Durán, F. A. Iglesias, S. K. Solanki +31
We present off-limb spectroscopy using low-straylight data from the Sunrise Spectropolarimeter and Imager (SUSI) onboard the Sunrise III stratospheric solar observatory. A spatial…
Delayed, Line-dependent Reorganization of Pore Oscillations Following a Compact C8.2 Flare Observed by Sunrise III/SUSI
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +34
Magnetic oscillations permeating the solar atmosphere can be altered by flares. This could be due to changes in the atmospheric magnetic waveguide, the thermodynamic stratification…
Sunrise III/SUSI reveals extended and spectrally structured Ca II K emission above the solar limb
Ivan Milić, Christopher M. J. Osborne, Francisco A. Iglesias +32
The Sunrise III/SUSI instrument performed a sit-and-stare observation of the off-limb emission in the Ca II K line core, with a combination of excellent temporal and spectral resol…
Origin of small-scale evaporation flows deep in the chromosphere during a solar flare
L. P. Chitta, H. N. Smitha, F. A. Iglesias +29
Flares are caused by an abrupt release of magnetic energy in the solar atmosphere. Plasma heated to well over 10 MK filling the post-flare corona originates from a rapid heating an…
Chromospheric Dynamics of an Umbral Flare Kernel - Based on Coordinated SUNRISE III SCIP and Domeless Solar Telescope Observations
Ayumi Asai, Satoru UeNo, Takuma Matsumoto +34
We report imaging spectroscopic observations of an M1.4 solar flare obtained during a coordinated observation between the infrared spectropolarimeter SCIP onboard the SUNRISE-III b…
Horizontal Magnetic Fields Dominate the Quiet Sun Internetwork in Sunrise III Observations. Evidence from Traditional and Transformer-Based Inversions
Ryan J. Campbell, Carlos Quintero Noda, Manuel Collados +32
The relative prevalence of horizontal and vertical magnetic fields in the quiet-Sun internetwork remains debated, owing to the weak linear polarisation signals that make the inferr…
Magnetic Field Stratification in Active-Region Plage from Ca II K and Ca II 8542 Å Spectropolarimetry
Iñigo Juanikorena Berasategi, Ernest Alsina Ballester, Javier Trujillo Bueno +31
We investigate the height variation of the line-of-sight (LOS) magnetic field in solar active-region (AR) plage from the upper photosphere to the upper chromosphere using co-spatia…
Vector Magnetic Field associated with an Active Region Filament Observed by SUNRISE III/SCIP in the Ca II 8542 Å Line
Takuma Matsumoto, Yukio Katsukawa, Masahito Kubo +38
We report high-spatial-resolution spectropolarimetric observations spatially associated with a solar filament, obtained with the SUNRISE Chromospheric Infrared spectro-Polarimeter…
Multi-line Wave Signatures in a Sunspot from Near-UV Sunrise III/SUSI Observations
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +32
Magnetohydrodynamic waves redistribute energy in magnetic structures of the lower solar atmosphere, yet constraints on how wave power and dominant frequencies are organised above s…
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…
Quantifying the effect of passband on observations in the Ca II K line
Ajay Kumar Yadav, Theodosios Chatzistergos, Natalie Krivova +33
Full-disk observations of the Sun in the Ca II K line have been carried out since the late 19th century at various observatories worldwide. These long-term records of solar activit…
The Sunrise Chromospheric Infrared Spectro-Polarimeter SCIP: an instrument for SUNRISE III
Y. Katsukawa, J. C. del Toro Iniesta, S. K. Solanki +54
The Sunrise balloon-borne solar observatory is equipped with a one-meter aperture optical telescope, offering a unique platform for uninterrupted seeing-free observations across ul…
Diagnostic capabilities of spectropolarimetric observations for understanding solar phenomena I. Zeeman-sensitive photospheric lines
C. Quintero Noda, P. S. Barklem, R. Gafeira +7
Future ground-based telescopes will expand our capabilities for simultaneous multi-line polarimetric observations in a wide range of wavelengths, from the near-ultraviolet to the n…
Diagnostics for spectropolarimetry and magnetography
Jose Carlos del Toro Iniesta, Valentín Martínez Pillet
An assessment on the capabilities of modern spectropolarimeters and magnetographs is in order since most of our astrophysical results rely upon the accuracy of the instrumentation…
The Imaging Magnetograph eXperiment (IMaX) for the Sunrise balloon-borne solar observatory
V. Martinez Pillet, J. C. del Toro Iniesta, A. Alvarez-Herrero +39
The Imaging Magnetograph eXperiment (IMaX) is a spectropolarimeter built by four institutions in Spain that flew on board the Sunrise balloon-borne telesocope in June 2009 for almo…
Quiet-Sun intensity contrasts in the near ultraviolet
