Takeshi Sakanoi We report the Jovian H3+ auroral dynamics based on the data taken with IRTF/CSHELL and Subaru/IRCS, and the Io’s volcanic gases measured by T40 and T60 telescopes at Haleakala, Hawaii. We also report the initial result on the Jovian infrared aurora and mid- and low-latitude observation recently observed by IRTF/ISHELL. Continuous monitoring is essential to understand the planetary atmospheric phenomena, and therefore, we carried out Jovian H3+ auroral measurements for these ten years. Distribution of ion winds and intensity in the Jovian polar region were estimated and their solar wind response was examined. On the other hand, thanks to the AO capability on Subaru/IRCS, we found the precise patchy auroral structure showing a periodic variation with several minutes in the Jovian polar cap region. Further, we have own T40 and T60 telescope facilities at the summit of Mt. Haleakala, and monitor the Io’s torus originated from volcanic activity on Io. In this presentation, we give the long and short term variations of Io’s torus using the data with the Haleakala telescopes in conjunction with ISAS Hisaki space EUV telescope. In addition, we also give the current status of the PLANETS telescope project on Haleakala. This is a 1.8m off-axis telescope, which is under the international consortium mainly formed with IfA/UH and KIS (Germany). The low-scattering light capability of PLANETS will give us unique opportunity to investigate faint emissions surrounding bright object, such as Io torus and exoplanetary atmosphere.
