Introduction Solar corona SXT Magnetically Dominated Source of solar wind Solar flares and Corona Mass Ejection(CME) Space weather forecast

Introduction Why X-ray? We can see the magnetic structure of the solar corona Why 3D? the origin of coronal activity is closely related to 3D configuration of magnetic fields

Introduction To know the three dimensional structure of the solar corona… STEREO (2006-) reveal three dimensional structure of solar corona using simultaneous observation with two satellites. 100” Aschwanden et al.(2008)
