Chromospheric velocities in an M3.2 flare using He I 1083.0 nm and Ca II 854.2 nm
C. Kuckein, M. Collados, A. Asensio Ramos +6
We study the chromospheric LOS velocities during the GOES M3.2 flare (SOL2013-05-17T08:43) using simultaneous spectroscopic data of the He I 1083.0 nm triplet and Ca II 854.2 nm li…

Multi-wavelength spectropolarimetric observations of AR13724 performed by GRIS
C. Quintero Noda, J. C. Trelles Arjona, T. del Pino Alemán +10
Multi-line spectropolarimetric observations allow for the simultaneous inference of the magnetic field at different layers of the solar atmosphere and provide insight into how thes…
