摘要: We study the high frequency dynamics in braided magnetic structure of an active region (AR 11520) moss as observed by High-Resolution Coronal Imager (Hi-C). detect quasi periodic flows and waves these structures. search for while looking at power maps region. find that shorter periodicites (30 - 60 s) are associated with small spatial scales which can be resolved Hi-C only. wide range velocities from 13 185 km/s regions. This interpreted plasma outflows reconnection sites. also presence short period large amplitude transverse oscillations Such could triggered or such oscillation may trigger reconnection.
