Magneto-acoustic oscillations observed in a solar plage region
Cao, Wenda; Xu, Zhe; Ji, Kaifan +4 more
We gave an extensive study for the quasi-periodic perturbations on the time profiles of the line of sight (LOS) magnetic field in 10 × 10 sub-areas in a solar plage region (corresponds to a facula on the photosphere). The perturbations are found to be associated with the enhancement of He I 10830 Å absorption in a moss region, which is connected t…
Observation of solar coronal heating powered by magneto-acoustic oscillations in a moss region
Ji, Kai-Fan; Hashim, Parida; Hong, Zhen-Xiang +3 more
In this paper, we report the observed temporal correlation between extreme-ultraviolet (EUV) emission and magneto-acoustic oscillations in an EUV moss region, which is the footpoint region only connected by magnetic loops with million-degree plasma. The result is obtained from a detailed multi-wavelength data analysis of the region with the purpos…
Predicting the CME arrival time based on the recommendation algorithm
Luo, Bingxian; Liu, Zhu; Li, Ming +9 more
CME is one of the important events in the sun-earth system as it can induce geomagnetic disturbance and an associated space environment effect. It is of special significance to predict whether CME will reach the Earth and when it will arrive. In this paper, we firstly built a new multiple association list for 215 different events with 18 character…
