| Outline of Final Research Achievements |
In conjunction with the solar maximum, attempts were made to monitor Jupiter's infrared auroral activities from high-altitude observing facilities in Hawaii. Jupiter's rotational axis was most tilted from the normal to ecliptic plane at this time period. In such conditions, the IMF (mostly in the ecliptic plane) can be felt by the planet as northwar or southward magnetic fields, resulting in possible enhancement of magnetic reconnections. In the first half of the period, we tried to use a telescope atop Mauna Kea (Hawaii Island), and later half a telescope atop Haleakara (Maui Island). Due to troubles with the telescopes, Jupiter's aurora was not observed. Instead, we successfully obtained Jupiter and its satellite Io data (for monitoring volcanism on Io) in shorter infrared wavelengths. The emissions from Venus' nightside disk were also observed. These will reinforce future collaborations between space missions and high-altitude observing facilities.
