We present preliminary results of a study aimed at building a SUMER atlas for prominences. Using the atlas as reference, further studies can be addressed at deriving prominence properties, such as DEM distribution and anomalies in element abundances. Moreover, a comparison with previous atlas (e.g. Curdt et al., 2001) of other solar regions can be made. An extended prominence was observed with SUMER in the South-West solar limb in October 1999. A full spectrum was obtained in the waveband 790 - 1600 Å. After dealing with off-limb scattered light, the data are processed using multi-Gaussian fitting in order to derive the spectral properties of the observed structure. These properties are then also compared with those of the Quiet Sun area observed in the same wavelength range.
