<p>The FP7 Heliospheric Cataloguing, Analysis and Technique Service (HELCATS) project capitalises on European expertise in heliospheric imaging built up over the last decade, particularly by lead involvement in NASA’s STEREO mission, whilst also exploiting the vast wealth of long established European expertise in such areas as solar and coronal imaging, as well as the interpretation of in-situ and radio measurements of solar wind phenomena.</p><p>The HCME_WP2 is a catalogue of manually identified CME events observed by the STEREO A and B heliospheric imaging cameras. This catalogue underpins the other work within the project by providing a complete list of CMEs detected by HI. These are then assessed and modelled using different techniques as part of other work packages within the project.</p><p>Version 05 of this catalogue is the latest formal release and covers the period from April 2007 to September 2017. Event IDs are tied to the corresponding event and will not change in future versions even if events are added or removed.</p
