Two-sided Loop Solar Jet Driven by the Eruption of a Small Filament in a Big Filament Channel
Similar to the cases of anemone jets, two-sided loop solar jets can also be produced by either flux emergence from the solar interior or small-scale filament eruptions.

Supra-arcade Downflows in an Extensive Fan Associated with a Giant Quiescent Solar Filament Eruption
We investigate the aftermath of a giant quiescent solar filament eruption on 2023 December 24. One feature of the eruption is an extensive fan above the filament channel that is about 3 times as wide as similar structures that appear above active regions

The Noneruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, since such eruptions frequently drive coronal mass ejections that impact the heliosphere.

Investigating an Erupting Metric-decimetric Radio Depression and Its Physical Origin
We present direct metric-decimetric radio imaging observations of a fascinating quiescent filament eruption on 2024 March 17 using data from the DAocheng Radio Telescope, with a combination of the Solar Dynamics Observatory and the Chinese H α Solar ...

Rotation of a Solar Jet Driven by Plasma Flow along Helical Magnetic Fields in an Active Region
Solar jets, collimated plasma ejections driven by magnetic reconnection, play a vital role in energy transport and coronal heating. While rotational motions in jets are often attributed to magnetic field untwisting, alternative explanatory mechanisms ...

The Eruptive Duality of a Filament on 2023 April 21
Here we study a filament eruption on 2023 April 21. The filament was composed of two segments, named S1 and S2. Initially, the brightening and bidirectionally plasmoid flows appeared inside S1, and then the west part of S1 (WS1) experienced rapid rising ...

Automated High-Precision Recognition of Solar Filaments Based on an Improved U2-Net
Solar filaments are a significant solar activity phenomenon, typically observed in full-disk solar observations in the H-alpha band. They are closely associated with the magnetic fields of solar active regions, solar flare eruptions, and coronal mass ...
