Abstract

Moving Magnetic Features (MMFs) are small magnetic features moving in a moat, which is a ring of weak line-of-sight magnetic fields surrounding a sunspot Despite the extensive study on the characteristics of MMFs since their discovery more than 35 years ago, their effect on the high atmosphere has never been investigated. In this paper, we would like to show for the first time the detected upper-atmospheric oscillations and flows associated with a MMF. The oscillations may be excited inside the MMF and propagated to the atmosphere along the magnetic field tubes of the MMF. The results indicate that MMF, despite being small, is capable of influencing the dynamic behaviors in the atmosphere at least up to the transition region.
