Who? EU FP7: GA no: 606692
Why? • FP7 HELCATS (1stMay 2014 ─ 1st May 2017) • Capitalises on European expertise in heliosphericimaging (esp. STEREO) - also exploiting the wealth of European experience in solar and coronal imaging and the interpretation of in-situ and radio measurements of solar wind phenomena. • Coordinated effort to produce a unique benchmark study of transients in the heliosphere, their sources and impacts, including assessment of models and methods EU FP7: GA no: 606692

What? • The general aims of HELCATS are to: • catalogue transient (CME) and background (CIR/SIR) structures imaged in the heliosphere by STEREO/HI, including estimated kinematic properties from established and speculative techniques; • verify these kinematic properties, hence assessing the validity of the techniques, by comparing with solar source/coronal observations, and in-situ measurements at multiple points in the heliosphere; • assess the potential for initialising advanced numerical models based on the derived kinematic properties of both the transient and background solar wind; • assess the complementarity of combining heliospheric imagery with radio-based methods to detect structures and diagnose processes in the heliosphere (IPS and Type II radio bursts); • provide the scientific community with easy access to HELCATS catalogues and methodologies, enabling a much wider exploitation and understanding of heliospheric imaging observations.
