Main Objective: Complementary observations in support of SPICE and EUI during quadrature for composition and dynamics studies
Scientific Justification: Solar Orbiter's orbit will bring it into quadrature with the Earth on 17 August 2017, allowing for a stereoscopic view of a joint target with SPICE, EUI, Hinode and IRIS. The focus of the SPICE observations will be composition studies and some dynamics. The line coverage of SPICE is complementary to that of EIS and IRIS, which makes the composition measurements of particular interest in mapping the ion abundance as a function of height for the investigation of sources of the slow or fast wind (Antonucci et al., 2006).
