Two Quasi-periodic Fast-propagating Magnetosonic Wave Events Observed In Active Region NOAA 11167

摘要: We report a detailed observational study of two quasi-periodic fast-propagating (QFP) magnetosonic wave events occurred on 2011 March 09 and 10, respectively. Interestingly, both the have trains (WTs): one main strong (WT-1) whereas second appears small weak (WT-2). Peculiar common characteristics are observed, namely: 1) QFP waves accompanied with brightenings during whole stage eruptions; 2) nearly propagating along same direction; 3) EUV found to be associated events. Investigating various aspects target events, we argue that: event is flux rope eruption stage; produces new filament-like (FL) dark feature; ripples WT-2 seem result from different triggering mechanisms. Based obtained results, propose that funnel-like coronal loop system indeed playing an important role in WT-1 waves. The development can explained as due dispersion front. co-existence offer thereby significant opportunity reveal what driving mechanisms structures tightly related
