摘要We analyze a case of transverse oscillation of a filament triggered by an extreme ultraviolet (EUV) wave on 2011 September 7 observed by the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager (HMI) aboard the Solar Dynamics Observatory (SDO). The EUV wave first appeared at 22:35 UT after a filament (F1) eruption in the NOAA active region 11283 and then propagated toward the northwest with a speed of 690 km s-1. When the EUV wave propagated through another filament (F2), it caused F2 to oscillate transversely. The oscillation period and damping time are calculated by a damped cosine function, and they are around 1140 s and 5920 s respectively. Based on coronal seismology, we estimate the average values of magnetic fields inside and outside the oscillating filament, about 17.6 G and 7.4 G respectively.
