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…
On the ratios of \ion{Si}{4} lines (1394/1403) in an emerging flux region
Durgesh Tripathi, V. N. Nived, Hiroaki Isobe +1
The resonance lines of \ion{Si}{4} formed at 1394 and 1403 Å are the most critical for the diagnostics of the solar transition region in the observations of the Interface Region…
Intense geomagnetic storm during Maunder minimum possibly by a quiescent filament eruption
Hiroaki Isobe, Yusuke Ebihara, Akito D. Kawamura +2
The sun occasionally undergoes the so-called grand minima, in which its magnetic activity, measured by the number of sunspots, is suppressed for decades. The most prominent grand m…
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…
