Small-scale Turbulent Motion of the Plasma in a Solar Filament as the Precursor of Eruption
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +5
A filament, a dense cool plasma supported by the magnetic fields in the solar corona, often becomes unstable and erupts. It is empirically known that the filament often demonstrate…
Relationship between three-dimensional velocity of filament eruptions and CME association
Daikichi Seki, Kenichi Otsuji, Takako T. Ishii +2
It is widely recognised that filament disappearances or eruptions are frequently associated with Coronal Mass Ejections (CMEs). Since CMEs are a major source of disturbances of the…
SMART/SDDI Filament Disappearance Catalogue
Daikichi Seki, Kenichi Otsuji, Takako T. Ishii +8
This paper describes a new SMART/SDDI Filament Disappearance Catalogue, in which we listed almost all the filament disappearance events that the Solar Dynamics Doppler Imager (SDDI…
Small-scale motions in solar filaments as the precursors of eruptions
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +3
Filaments, the dense cooler plasma floating in the solar corona supported by magnetic fields, generally exhibit certain activations before they erupt. In our previous study (Seki e…
Space Weather Prediction from the Ground: Case of CHAIN
Daikichi Seki, Satoru Ueno, Hiroaki Isobe +5
In this article, we insist on the importance and the challenges of the prediction of solar eruptive phenomena including flares, coronal mass ejections (CME), and filament eruptions…
Increase in the amplitude of line-of-sight velocities of the small-scale motions in a solar filament before eruption
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +3
We present a study on the evolution of the small scale velocity field in a solar filament as it approaches to the eruption. The observation was carried out by the Solar Dynamics Do…
