WebOne important part of the research is to measure the velocity of the CME and trace its acceleration as it leaves the Sun. This is done by tracing individual features in the CME and measuring their positions as a function of time. One of the main ways we observe CME's is with coronagraphs. 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.
