With the purpose of detecting periodic oscillations or waves in a quiescent prominence, temporal variations ofa CaII K line profile have been studied. The most conspicuous phenomenon found here is the fact that the edge of the prominence showed, over some 20000 km along the spectrograph-s/it, period
A quiescent prominence has been observed with the MSDP spectrograph at the Pic du Midi Observatory. He profiles are obtained simultaneously in a 2D field, allowing a statistical analysis. The standard deviations of Doppler shifts and line widths are investigated as functions of the line intensity. T
