HELCATS - Heliospheric Cataloguing and Analysis Service

HELCATS is a European project capitalizing on expertise in heliospheric imaging to study transients in the heliosphere. It involves cataloging, analyzing, and linking solar wind phenomena through various datasets and models. The project aims to understand the nature and impact of heliospheric events and improve numerical modeling based on observation data. HELCATS provides access to catalogues and methodologies, enabling broader utilization of heliospheric imaging observations.

  2. Who? EU FP7: GA no: 606692

  3. 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

  10. Overview – Initialising advanced numerical models based on the kinematic properties of STEREO/HI CMEs and CIRs Transform the STEREO/HI CME and CIR catalogues into more advanced catalogues of simulation results of CMEs and CIRs, optimised through the direct assimilation of the heliospheric imagery

  14. 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.
