AB: The geometric localization technique [Pizzo and Biesecker, 2004] utilizes a series of lines of sight from two space-based observatories in order to determine gross propagation characteristics of coronal mass ejections (CMEs). We have set up this tool to work specifically with STEREO (Solar TErrestrial RElations Observatory) coronagraph observations. Here, we employ this technique to the CME of 21 August 2007 and present results on the speed and direction of propagation for this CME. This technique meets a need within the space weather community for a means to accurately determine the gross properties of Earth-directed CMEs from a near-real- time data stream, such as the one provided by the STEREO Space Weather Beacon.
