From 2022 March 18-21, active region (AR) 12967 was tracked simultaneously by Solar Orbiter (SO) at 0.35 au and Hinode/EIS at Earth. During this period, strong blue-shifted plasma…
First Perihelion of EUI on the Solar Orbiter mission
D. Berghmans, P. Antolin, F. Auchère +34
Context. The Extreme Ultraviolet Imager (EUI), onboard Solar Orbiter consists of three telescopes: the two High Resolution Imagers in EUV (HRIEUV) and in Lyman-α (HRILya), and the…
Eruption and propagation of twisted flux ropes from the base of the solar corona to 1 au
F. Regnault, A. Strugarek, M. Janvier +3
Interplanetary Coronal Mass Ejections (ICMEs) originate from the eruption of complex magnetic structures occurring in our star's atmosphere. Determining the general properties of I…
Plasma composition measurements in an active region from Solar Orbiter/SPICE and Hinode/EIS
David H. Brooks, Miho Janvier, Deborah Baker +28
A key goal of the Solar Orbiter mission is to connect elemental abundance measurements of the solar wind enveloping the spacecraft with EUV spectroscopic observations of their sola…
Exploring the Limits of Synthetic Creation of Solar EUV Images via Image-to-Image Translation
