Solar Flare Telescope

The Sun gives us many things including light and heat. The Sun is not the same all the time: an explosion called a solar flare occurs and the number of sunspots changes on an 11-year cycle. These activities of the Sun are strongly related to the solar magnetic field.

The Solar Flare Telescope has observational instruments with the latest technology. One of them observes polarized infrared light in order to reveal the relationship between solar activities and the solar magnetic field.

The Solar Flare Telescope is not included in the regular open course of Mitaka Campus and is not open to the public.
