abstract = "We present the first multi-viewpoint coronal mass ejection (CME)
catalog. The events are identified visually in simultaneous total
brightness observations from the twin SECCHI/COR2 coronagraphs on
board the Solar Terrestrial Relations Observatory mission. The
Multi-View CME Catalog differs from past catalogs in three key
aspects: (1) all events between the two viewpoints are
cross-linked, (2) each event is assigned a physics-motivated
morphological classification (e.g., jet, wave, and flux rope), and
(3) kinematic and geometric information is extracted
semi-automatically via a supervised image segmentation algorithm.
The database extends from the beginning of the COR2 synoptic
program (2007 March) to the end of dual-viewpoint observations
(2014 September). It contains 4473 unique events with 3358 events
identified in both COR2s. Kinematic properties exist currently for
1747 events (26% of COR2-A events and 17% of COR2-B events). We
examine several issues, made possible by this cross-linked CME
database, including the role of projection on the perceived
morphology of events, the missing CME rate, the existence of cool
material in CMEs, the solar cycle dependence on CME rate, speeds
and width, and the existence of flux rope within CMEs. We discuss
the implications for past single-viewpoint studies and for Space
Weather research. The database is publicly available on the web
including all available measurements. We hope that it will become
a useful resource for the community.",
