Abstract:

SUNRISE III to be flown in 2024 is the third flight of the international balloon project Sunrise. The team led by NAOJ provided the near-infrared spectro-polarimeter SCIP through international collaboration with the Spanish and German teams. By combining the 1-meter aperture telescope, SCIP will simultaneously observe many spectral lines in near-IR including two of the chromospheric Ca II infrared triplet lines, upper photospheric K I D1 and D2 lines, and multiple photospheric Fe I lines with a resolution of 0.2” which is higher than that of the HINODE Solar Optical Telescope. The observation provides height-dependent magnetic and velocity structures and their time evolution from the photosphere to the chromosphere and clarifies the transport and dissipation processes of magnetic energies. By synthesizing the spectrum lines observed with SCIP, we demonstrated that we could aim to measure polarization signals from twisted magnetic fields driving a chromospheric jet. The other target is an Ellerman bomb to detect reconnection jets and their relationship with surrounding magnetic fields. We present here the capability of SCIP and its science cases.
