We present an observational study of the relationship between the acceleration of eruptive prominences and the speed of their associated CMEs during the period 1998--2001 using observations from the Mauna Loa Solar Observatory (MLSO) and the SOHO satellite. We have used MLSO/CHIP data in the HeI 1083 nm line and the MLSO/PICS in the Hα 656.3 nm line to identify eruptive prominences that show a clear association to CMEs seen by the MLSO/MarkIV and SOHO/LASCO coronagraphs. Events occurring at the limb, or near the limb have been selected for this study to minimize projection effects. Ground based observations have been used to determine the projected radial velocity and acceleration of the eruptive prominences, while SOHO/LASCO observations have been used to determine the same parameters of the corresponding CMEs. The principal goal of this study is to allow the use of line--of--sight velocity (and acceleration) measurements of erupting filaments obtained by the MLSO/CHIP instrument to infer the speeds of earth--directed CMEs. In particular, we are interested in determining whether the faster, and more geoeffective CMEs can be associated with a specific class of eruptive prominences/filaments. It is also hoped that this study will shed light on the acceleration mechanisms of CMEs.
