WP3 Catalogue

This catalogue builds on the HI identified CME catalogue produced under WP2. Where possible, time elongation tracks are extracted for each CME along a defined position angle corresponding approximately to the apex of the CME. Single spacecraft geometric fitting techniques (see Davies et al., 2012; doi:10.1088/0004-637X/777/2/167) are used to determine the kinemtatic properties (direction, speed and launch time) for three different simple assumptions of the CME morphology. The result is a super-set of the WP2 catalogue containing both the observed parmeters and the derived kinematics. Please see Barnes et al., 2019 (doi:10.1007/s11207-019-1444-4) for further information and caveats related to this catalogue.

This is version: 06 of the catalogue, released 2019-03-18, last updated 2020-10-08. The catalogue is based on version 6 of the WP2 catalogue. The latest version includes events to the end of September 2020 on STEREO-A. Note that there is a gap of approximately 1 year in STEREO-A data from October 2014 when the spacecraft passed behind the Sun. Data from STEREO-B are not available after Septmeber 2014 since contact with the spacecraft has yet to be re-established.

The catalogue can be downloaded in several formats (Fixed format ASCII, JSON, VoTable XML).

The time-elongation profiles used for the fitting for all events can be downloaded as a .tar.gz file (HCME_WP3_V06_TE_PROFILES.tar.gz)

catalogue contains the following columns (by default only a subset are shown above but all will be included when you copy or download the data. Use the Show/hide columns option to display the required selection. Events with quality classification of "poor" are not shown):

ColumnDescription
IDThe unique identifer for the observed CME.
Date [UTC] The date and time of the first observation of the CME in HI1 camera.
SCThe observing STEREO spacecraft, (A=Ahead or B=Behind).
L-N Indicator that CME extends beyond the northern edge of the field-of-view (< for sc A, > sc B, blank if edge within FOV).
PA-N [deg] The most northern position angle of the CME span.
L-S Indicator that CME extends beyond the southern edge of the feld-of-view (> for sc A, < for sc B, blank if edge within FOV).
PA-S [deg] The most southern position angle of the CME span.
Quality

A measure of "good", "fair" or "poor", that indicates the quality of the CME observation and confidence that the eruption is by definition a CME. It is recommended that Poor events are not used for CME based studies.
