Context. The nature of loops is still a matter of debate with several explanations having been put forward. Simultaneous spectral and imaging
data have the capacity to provide a new insight into mass motions, dynamics and energetics of loops.
Aims. We report on spectral data taken with the Solar Ultraviolet Measurements of Emitted Radiation spectrograph (SUMER) and imaging
data from the Transition Region and Coronal Explorer (TRACE) of a transient event which occurred in a cold loop, lasting a few minutes.
