Description
In this ARRival CATalog (ARRCAT), the arrivals of solar coronal mass ejections (CMEs) that were tracked by the STEREO heliospheric imagers are calculated. ARRCAT lists modeled arrivals of CMEs at various spacecraft and planets, based on the HIGeoCAT catalog of CMEs established at RAL Space, UK (R. A. Harrison, J. A. Davies, D. Barnes). It is a living catalog, updated about every 2 months.
