The catalog is accessed via the month-year matrix below. The number of events in each month are in parentheses. Clicking on the month cell reveals the list of events for that month along with their morphological and kinematic parameters (if available). Each event has a COR2-A and -B entry which is filled with '-999's if the event was undetected in that telescope. The kinematic parameters are derived either automatically via the supervised algorithm CORSET (event ID ending in 'c') or manually (event Id ending in 'm'). Details on the algorithm and parameter extraction are given in Balmaceda et al. (2017). The MVC Catalog is unique in providing a morphological classification for each event and viewpoint. The classification criteria are discussed in Vourlidas et al. (2017). The links in each column provide further information and/or data (e.g. filename lists, height-time points, etc.)
Col (2): Event ID. Ending denotes measurement method:
'c': CORSET; 'm' Manual; '': no measurements
Col (3): Date of first appearance in COR2
Col (4): Time of first appearance
Col (5): Morphology: 'F'= Flux Rope; 'L' = Loop; 'J'= jet; 'O'=Other; 'U'= Unknown; 'Z'=no detection; 'P'= Preceding CME; 'S'= Shock candidate
Col (6): angular separation of STEREO s/c (Deg)
Col (7): Central Position Angle of CME (CCW from Solar North)
Col (8): Angular Width (deg)
Col (9): Radial Speed (km/s)
Col (10): acceleration (km/s2)
Col (11): Expansion Speed (km/s)
Col (12): Expansion acceleration (km/s2)
CS 'Current sheet'
COL Possible collision with previous CME
DFL Likely deflection of the event within the FOV
DPL CME exhibits dimpled front
Faint Faint event; may affect type assignment
FF Event fails/disappears before exiting COR2
FOV Front Bright front; may be evidence of pileup
GAP Data gap
Ha Bright emission (likely H-alpha emission)
HAL Halo CME
KEY Keyhole-hole shaped CME
OFL Outflowing material at the back of the CME
OVR Event partially overlaps with another CME
PRM Prominence material (filamentary structures)
SB Streamer Blowout following CME
SEP Solar Energetic Particle event
SLB Side-lobe Operations
SUR Surge-like eruption

Other COR2 CME Catalogs
There exist other SECCHI, and in particular COR2-based, CME catalogs. Some are based on automated detection algorithms and some are built manually. Below is a list with all the catalogs we are aware of along with some brief note. The list is subject to revision.
- COR2 CME Catalog at the University of Göttingen (2007 – 2011). Manual. Contains list of 'best of' events appropriate for 3D reconstruction.
- SEEDS COR2 CME Catalog at the George Mason University (2007 – present). Automated. Not dual-view detection ( COR2-A and B detections are made independently).
- CACTus COR2 CME Catalog at the Naval Research Laboratory (2007 – present). Automated. Not dual view detection.
Other CME Catalogs
A list of catalogs based on single-viewpoint observations from the coronagraphs and imagers on board the STEREO and SOHO spacecraft.
|SECCHI COR1 CME Catalog||CDAW LASCO Catalog|
|SECCHI HI Catalog||CORIMP Catalog|
|SEEDS LASCO/C2 Catalog|
|CACTus LASCO/C2 Catalog|
|ARTEMIS LASCO/C2 Catalog|
The catalog and associated data are publicly available per the STEREO mission Data Management Plan and comprise part of the SECCHI team's higher level data products.
