Understanding the Lyα Emission Observed by the Solar Disk Imager Aboard the Advanced Space-based Solar Observatory
Yiliang Li, Ping Zhang, Zhengyuan Tian +12
The H I Lyman-alpha (Ly) emission, with a wavelength of 1216 Å, is the brightest solar ultraviolet (UV) line. However, comprehensive observations of the Ly emission line acro…
Asymmetric Hard X-ray Radiation of Two Ribbons in a Thermal-Dominated C-Class Flare
Guanglu Shi, Li Feng, Jun Chen +9
The asymmetry in hard X-ray (HXR) emission at the footpoints (FPs) of flare loops is a ubiquitous feature closely associated with nonthermal electron transport. We analyze the asym…
Association between a Failed Prominence Eruption and the Drainage of Mass from Another Prominence
Jianchao Xue, Li Feng, Hui Li +31
Sympathetic eruptions of solar prominences have been studied for decades, however, it is usually difficult to identify their causal links. Here we present two failed prominence eru…
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…
