Solar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence
Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
متن کاملA spectroscopic study of coronal dimming associated with a coronal mass ejection
Extreme ultraviolet spectroscopic observations of one coronal mass ejection event are used to examine the onset phase of the eruption. We find significant dimming of million K plasmas in the low corona under the ascending CME, the activation of an adjacent prominence and 2 million K ‘hot spots’ which may be associated with the CME footpoints. In particular, we show that the dimming is due to a ...
متن کاملMechanisms of Solar Coronal Heating
A major problem in astrophysical plasma physics is to explain how the outer atmosphere, the corona, ofthe sun is heated to temperatures of millions of degrees Kelvin. It is accepted that the heating mechanism is magnetic, with the energy source being turbulent motions below the solar surface. Two classes of theory are proposed, according to the timescale of the driving motions in relation to th...

متن کاملCoronal mass ejection: key issues
Coronal Mass Ejections (CMEs) have been addressed by a particularly active research community in recent years. With the advent of the International Heliophysical Year and the new STEREO and Hinode missions, in addition to the on-going SOHO mission, CME research has taken centre stage in a renewed international effort. This review aims to touch on some key observational areas, and their interpre...
