Multiwavelength Observations for a Double-decker Filament Channel in AR 13102
Yin Zhang, Baolin Tan, Quan Wang +8
We present the observational evidence of the existence of a double-decker filament channel (FC) by using observations in extreme ultraviolet and Hα wavelengths. For both FCs, the e…
Minifilament Eruptions as the Last Straw to Break the Equilibrium of a Giant Solar Filament
Hechao Chen, Hui Tian, Quanhao Zhang +8
Filament eruptions are magnetically driven violent explosions commonly observed on the Sun and late-type stars, sometimes leading to monster coronal mass ejections that directly af…
Correction for the Weakening Magnetic Field within the Sunspot Umbra Observed by ASO-S/FMG
Haiqing Xu, Jiangtao Su, Suo Liu +6
The magnetic field inside the sunspot umbra, as observed by the Full-disk MagnetoGraph (FMG) onboard the Advanced Space based Solar Observatory (ASO-S), was found to be experiencin…
Observation of a large-scale filament eruption initiated by two small-scale erupting filaments pushing out from below
Yongliang Song, Jiangtao Su, Qingmin Zhang +9
Filament eruptions often result in flares and coronal mass ejections (CMEs). Most studies attribute the filament eruptions to their instabilities or magnetic reconnection. In this…
Persistent Upflows and Downflows at Active Region boundaries Observed by SUTRI and AIA
Yuchuan Wu, Zhenyong Hou, Wenxian Li +6
Upflows and downflows at active region (AR) boundaries have been frequently observed with spectroscopic observations at extreme ultraviolet (EUV) passbands. In this paper, we repor…
