Transverse oscillations in a coronal loop arcade

Erwin Verwichtee ,  University of Warwick

The analysis of TRACE observations of transverse oscillations in a coronal post flare loop arcade are presented.
The oscillation parameters for nine loops are deduced as a function of distance along the loop.
The oscillations are interpreted as standing fast magnetoacoustic kink oscillations
and the coronal magnetic field strength is derived from the phase speed.
Furthermore, the relationship between the oscillation decay time and the period is explored,
compared with previous observations and is discussed in terms of proposed mechanisms that explain the rapid decay times.
