Current status of Jovian magnetosphere observation by EXCEED onboard HISAKI

Abstract:

EXCEED is an existing Earth-orbiting spectrometer working in the EUV spectral range from 50 nm up to 150nm, still observing solar planets.
Hisaki with EXCEED was successfully launched by epsilon rocket from Uchinoura in 2013 September and has competeled approximately 2-year investigations of solar planets.
The inner magnetosphere of Jupiter is one of the most important targets for EXCEED. Especially, coupling between Io-Plasma-Torus (IPT) and aurora is an interesting topic,
and indeed EXCEED spent much time of observations.
Internal-driven aurora, IPT responses to the auroras, periodicity of IPT brightness, and SW dependence of IPT activity will be presented.
