Haleakala Long-term Monitoring Program

Overview

We are making long-term monitoring of faint emissions from exosphere/magnetosphere of planets (Jupiter, Mercury, Saturn, etc.) using telescopes at Haleakala observatory. If you are interested in the following observation data or in collaboration with us, please contact PI(s) by e-mail (_at_: should be changed to "@").
