The plasma diagnostics of a quiescent prominence observed on June 12, 1997 with SUMER, CDS and EIT instruments aboard SOHO in the frame of Joint Observing Programme 9 has been made. Two sets of SUMER observations were taken in the four spectral lines Si IV 1393.755, 1402.770 (6-8 104 K) and O IV 1401.156, 1404.812 (1.7-2.0 105 K) at two different slit positions on the prominence body. The relative line-of-sight velocities using both Si IV 1393.755 and 1402.770 lines are derived. The electron density (derived from the intensity ratio of O IV 1401.156 to 1404.812 lines) in the prominence-corona interface is determined for both slit positions. CDS obtained 10 rasters in Si X 347.40, He I 584.33, Si X 356.04, Fe XVI 360.76, Mg IX 368.06, O V 629.73 lines covering a temperature range from 104 to 106 K. By analysing the CDS spectra in He I and O V ions the relative line-of-sight velocity maps with regards to the quiet sun are derived.
