Failed Eruption of a Filament as a Driver for Vertical Oscillations of Coronal Loops

Abstract

We present observations of a failed eruption of a magnetic flux rope recorded during the M6.2 flare of 14 July 2004. The observations were mainly made with TRACE 171 Å and 1600 Å filters. The flare was accompanied by a destabilization of a magnetic structure observed as a filament eruption. After an initial acceleration the eruption slowed down and finally was stopped by the overlying coronal loops. The observations suggest that the whole event is well described by the quadrupole model of a solar flare. The failed eruption stretched the loops lying above and then they were observed oscillating. We were able to observe clear vertical polarization of the oscillatory motion in TRACE images. The derived parameters of the oscillatory motion are the initial amplitude of 9520 km, the period of 377 s, and the exponential damping time of 500 s. Differences between the existing models and the observations have been found. The analyzed event is the second sample for global vertical kink waves found besides the first by Wang and Solanki (2004).
