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…
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 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…
Supergranulation and Poleward Migration of the Magnetic Field at High Latitudes of the Sun
L. P. Chitta, D. Calchetti, J. Hirzberger +26
Magnetoconvection at the solar surface governs the dynamics in the upper solar atmosphere and sustains the heliosphere. Properties of this fundamental process are poorly described…
Probing Solar Polar Regions
Yuanyong Deng, Hui Tian, Jie Jiang +45
The magnetic fields and dynamical processes in the solar polar regions play a crucial role in the solar magnetic cycle and in supplying mass and energy to the fast solar wind, ulti…
