Introduction



    Our field of research, called geomagnetism, has made great advances based on ground observations of the geomagnetic field, aurora, ionosphere, and cosmic rays. Moreover, direct observations of space by spacecraft beginning with Sputnik I Mission (1957) have expanded the regions of research rapidly. Many discoveries, such as, the radiation belt, the magnetosphere, the solar wind, and collision free stationary shocks, have revealed how dynamic the interplanetary space is and has revealed complex structures within which various phenomena occur. Today, research of these regions are called upper atmospheric physics, ionospheric-magnetospheric physics, interplanetary physics, planetary atmospheric physics, solar-terrestrial physics, and space physics.

    The spacecrafts Voyager I and II, which were launched in 1977, sounded Jupiter (1979), Saturn (V-I:1980, V-II:1981), Uranus (V-II:1986), and Neptune (V-II:1989), and continue to fly toward the boundary of the heliosphere sending us observational data. Regions of our research, which are observed directly by spacecrafts, are still expanding.

    In our laboratory, we research the following themes with analyses of data from ground-based observatories or satellites, numerical simulations, and development of instruments.

    We research and educate students in cooperation with the
Data Analysis Center for Geomagnetism and Space Magnetism, Graduate School of Science, Kyoto University.
