Automatic Coronagraph Image Classification with Machine Learning Methods

Zhang, Yan; Feng, Li; Li, Hui +5 more

The detection of Coronal Mass Ejections (CMEs) is an important prerequisite for establishing a CME event database and realizing the prediction of CME interplanetary propagation. The Lyman-alpha Solar Telescope (LST) aboard the ASO-S (Advanced Space-based Solar Observatory) satellite will be equipped with a white-light coronagraph. The images with …

Study of the Streamer Current Sheet with White-Light and UV Observations

Feng, Li; Li, Hui; Shi, Guang-lu +2 more

Current sheets (CSs) are the main region where magnetic reconnections can convert magnetic energy into plasma thermal and kinetic energies. We have studied a CS in the streamer occurred on 3 January 2003 by combining the White-Light (WL) images observed by the Large Angle and Spectrometric Coronagraph (LASCO) and the EUV spectra detected by the Ul…
