AB: The SECCHI HI1 coronagraph is providing impressive new data showing the evolution of CMEs as they propagate towards Earth. We have applied an optical flow technique to the HI1 data to estimate the projected velocity of the CME. The optical flow technique we applied has previously been used to analyze SOHO-LASCO-C2 coronagraphic data. Here, we present the analysis of two CMEs observed in HI1-A on 2007 April 20 and 2007 July 9.
