A Study on the Fast Solar Corona Extreme-ultraviolet Wave Associated with a Coronal Mass Ejection

Taking the advantage of high temporal and spatial resolutions of the Solar Dynamics Observatory (SDO) observations, we study a solar corona extreme-ultraviolet (EUV) wave associated with the coronal mass ejection (CME) on 2014 January 7. Our main purpose is to investigate the driving mechanism of this EUV wave, by analyzing the relation between the CME and the onset time and initial location of the EUV wave. Our result indicates that the EUV wave should be driven by the associated CME. By analyzing the time-slice images, we find that the wave has a speed of over 1 200 km·s−1. The observed fast EUV wave can be interpreted by the hybrid model proposed by Chen et al. (2002), and it corresponds to the fast component in Chen's model, i.e., the coronal Moreton wave.
