A detailed study of 2 well-observed CME events are presented. For a CME on 25-Jan 2007 we discuss the significance of the information from STEREO-B (from behind the limb of sun-earth line instruments) in calculating the position and time of the CME onset, and vital information on the state of the pre-CME corona. This study consists of a number of new observational features: the presence of a slow rising dark feature hours before the CME onset; the height-time profile of this feature in EUVI and COR pB images; the possibility of this feature existing post-CME; the post-CME 'loop-squashing' in EUVI; the height time pofile and hence height of maximum acceleration of the CME front; the position and temporal evolution of X-ray sources. We present a similar study for a 2nd CME observed on 07-Mar-2007. Both events seems to be excellent examples of flux-rope type events.
