ACME is an automatic monitoring tool that detects and characterizes coronal mass ejections in near-real time. It was originally developed as an effective way of summarizing time series of coronagraph images that preserves all the information about CME occurrence, their relative importance, and their sky plane angular size and direction. In combination with a detection algorithm, it can now estimate the sky plane velocity and rise alerts depending on the CME physical parameters. This poster shows how the summary images are computed and how to interpret them. The real-time plots for the last five days are made available in the web page of the Spanish Space Weather Service (SeNMEs) http://www.senmes.es/pub/ACME/acme_resumen.png
