On-disk signatures of eruptive activity from the Hinode mission Review Article

On-disk signatures of eruptive activity have been investigated for many years. These include filament eruptions, flares, coronal waves and dimmings. The Hinode mission is providing a new perspective on eruptive activity on the Sun and its linkage to the Earth. Despite being in a period of solar minimum since the launch of Hinode in September 2006, observations have been made of flares and coronal mass ejections (CMEs). A description of flare and CME triggers are presented, followed by a description of the impact of the eruption on the surrounding corona. A review of the more recent results achieved predominantly from the Hinode space mission are given. Some discussion of the future potential is described as a new solar cycle is beginning a slow start.
