Coronal mass ejections (CMEs) are major drivers of geomagnetic storms, which may cause severe space weather effects. Automating the detection, tracking, and three-dimensional (3D)…
Spectral and Imaging Observations of a C2.3 White-Light Flare from the Advanced Space-Based Solar Observatory (ASO-S) and the Chinese H Solar Explorer (CHASE)
Qiao Li, Ying Li, Yang Su +27
Solar white-light flares are characterized by an enhancement in the optical continuum, which are usually large flares (say X- and M-class flares). Here we report a small C2.3 white…

Zhichen Jing, Ying Li, Li Feng +26
Solar white-light flares (WLFs) are those accompanied by brightenings in the optical continuum or integrated light. The White-light Solar Telescope (WST), as an instrument of the L…
Global energetics of solar powerful events on 6 September 2017
Dong Li, Alexander Warmuth, Jincheng Wang +9
Solar flares and coronal mass ejections (CMEs) are thought to be the most powerful events on the Sun. They can release energy as high as 10^32 erg in tens of minutes,and could prod…
Spatially Resolved Moving Radio Burst in Association with an EUV Wave
Lei Lu, Li Feng, Weiqun Gan
Coronal mass ejections (CMEs) are large clouds of magnetized plasma ejected from the Sun, and are often associated with acceleration of electrons that can result in radio emission…
