The Heliospheric Cataloguing, Analysis and Techniques Service (HELCATS) project is one of the European
Union’s Seventh Framework Programme (EU FP7) projects. The project is primarily targeted to the cataloguing of
transient and background structures observed in the heliosphere by the visible-light Heliospheric Imagers (HIs) on
board the twin spacecraft STEREO mission, including identification of their source regions and in-situ signatures.
The current version of the HELCATS manually-generated Coronal Mass Ejection (CME) Catalogue contains more
than 1,000 CMEs observed between 2007 and 2016, and the current HELCATS Stream Interaction Region (SIR)
Catalogue contains signatures of nearly 200 co-rotating density structures in the ecliptic plane. HELCATS also
includes an assessment of the complementary nature of ground-based radio observations of interplanetary scintillation
(IPS), which is yielding catalogues of IPS features (from EISCAT/MERLIN/ESR and/or LOFAR data,
where available) that are being compared to the STEREO HI catalogues. Here we discuss the near-final status of
this aspects of HELCATS and provide any insights that have been gleaned from initial analyses of this joint cataloguing
exercise. Such insights relate, in particular, to the space-weather exploitation of these two complementary
observational techniques. For example, there are cases where a CME is imaged by the STEREO HI instruments
but then not detected using IPS, and vice versa, and preliminary investigations of these will be discussed.
