Outline of Final Research Achievements

Solar flares, the most energetic explosion in the solar system, are very spectacular. They are sometimes associated with coronal disturbance, that is, shocks, ejections, and waves in the corona, which affect seriously the solar-terrestrial environment, and therefore, they are very important for space weather researches. I have investigated comprehensively coronal disturbances associated with flares by using multi-wavelength data.
