Events List

The solar wind transient event list contains speeds and directions calculated from time-height 'j-plots' along the ecliptic for all solar wind transients that are seen to propagate into the outer H12 cameras field of view. As this list is derived semi-automatically it contains speeds and directions for both coronal mass ejections (CMEs) and co-rotating interaction (CIRs) and does not distinguish between them.

We also provide a link to the HELCATS data products catalogues.
