(Top) Clustered time series for four ICMEs from Nieves-Chinchilla et al. (2018) (in gray) during July 2004. It is noticeable that the orange cluster is associated with ejecta with a clear signature of a magnetic cloud, whereas the cyan cluster is associated with compressed fast wind and related to events where the magnetic cloud is not clearly defined. For the first three ICMEs, it is noticeable that we have a first phase where the slow wind is compressed (blue), followed by a fast compressed wind, and depending on the event, one has an orange cluster, which is associated with magnetic clouds. The exception is for the last ICME, where a strong shock occurred, and we have no compressed slow wind, but only compressed fast wind. (Bottom) Comparison between Xu & Borovsky (2015) classification. In this case, the Xu and Borovsky classification better matches the ICMEs.
