A coronal mass ejection (CME) was observed on 1997 September 9 by the MLSO Mark III K-coronameter (MK3) and by the LASCO C2/C3 and EIT instruments onboard the SOHO spacecraft. Magnetograms and EIT images obtained on days leading up to the eruption show a neutral line that appears to correspond to the site of the eruption. Hα images show the presence of a filament along the neutral line which subtends an angle of approximately 45(deg) with the local north-south meridional direction. Taken together, the data from these instruments provide a comprehensive, beginning-to-end record of the event within the 32 R_sun field of view. The motion of several features are tracked through the fields of view of MK3, C2, and C3. The CME exhibits the previously identified morphological features and dynamical properties consistent with those of an erupting magnetic flux rope. The LASCO images and magnetograms indicate that the flux rope axis was aligned with the neutral line approximately two days behind the west limb. Its apparent orientation provides an oblique view of an erupting flux rope, a view that has not been discussed previously. A theoretical flux rope model is used to understand the observed CME dynamics. Synthetic coronagraph images based on the model flux rope are constructed. Work supported by ONR, NASA, and NSF.
