Events List

We now provide two event lists. The first 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.

The second list is for CMEs only and was compiled by Richard Harrison through careful inspection of the images obtained from HI1 cameras. As such it is a more detailed list of CMEs, linking each to the appropriate transients seen in the first list where possible, and contains information about direction and extent of each CME in terms of solar position angle. Since this process is far more time-consuming, this list is currently only complete for CMEs occurring to the end of 2008.
