Webimagers and measured in situ by spacecraft such as ACE and Wind. With the launch of SOHO and STEREO, the availability of white-light imagers with wide ﬁelds-of-view has made it possible to associate eruptions observed in the corona to CMEs measured in situ at 1 AU [see for example the list by Richardson and Cane, 2010]. CMEs measured WebCMEs travel outward from the Sun at speeds ranging from slower than 250 kilometers per second (km/s) to as fast as near 3000 km/s.

WebWe take advantage of a recent study (Salman, Winslow, Lugaz, JGRA, 2024) identifying 45 CMEs measured in conjunction by two spacecraft in the inner heliosphere (MESSENGER, VEX, ACE/Wind, STEREO). For 42 events, there are plasma measurements near 1 AU that allow us to derive the expansion speed and the expansion parameter ζ. WebCMEs are diﬀerent from normal CMEs, which can not be merely explained by projection eﬀect, and the brightness of halo CMEs probably includes their driven (shock) waves.
