Evolution of the anemone AR NOAA 10798 and the related geo-effective flares and CMEs
We examine in detail the evolution of an anemone active region (AR) that emerged in a Coronal Hole and the related flares, CMEs, and the geomagnetic storm to elucidate how such a magnetic configuration works to generate a geo-effective flares/CMEs. We found that the fast CMEs are probably a consequence of the eruption inside a Coronal Hole from an sea anemone AR, and discuss the importance of ARs that show the anemone structure for the space weather studies.

Three Successive and Interacting Shock Waves Generated by a Solar Flare
We discovered three successive Moreton waves generated by a single solar flare. These waves were observed on 3 August 2005 with Solar Magnetic Activity Research Telescope (SMART) at Hida Observatory of Kyoto University.
