abstract = "The different appearances exhibited by coronal mass ejections
(CMEs) are believed to be in part the result of different
orientations of their main axis of symmetry, consistent with a
flux-rope configuration. There are observational reports of CMEs
seen along their main axis (axial perspective) and perpendicular
to it (lateral perspective), but no simultaneous observations of
both perspectives from the same CME have been reported to date.
The stereoscopic views of the telescopes onboard the
Solar-Terrestrial Relations Observatory (STEREO) twin spacecraft,
in combination with the views from the Solar and Heliospheric
Observatory (SOHO) and the Solar Dynamics Observatory (SDO), allow
us to study the axial and lateral perspectives of a CME
simultaneously for the first time. In addition, this study shows
that the lateral angular extent (L) increases linearly with time,
while the angular extent of the axial perspective (D) presents
this behavior only from the low corona to \≈5R\⊙,
where it slows down. The ratio L/ D\≈ 1.6 obtained here as
the average over several points in time is consistent with
measurements of L and D previously performed on events exhibiting
only one of the perspectives from the single vantage point
provided by SOHO.",
