We discuss how simultaneous observations by multiple heliospheric imagers (HIs) can provide some important information about the azimuthal properties of coronal mass ejections (CMEs) in the heliosphere. We propose two simple models of CME geometry that can be used to derive information about the azimuthal deflection and the azimuthal expansion of CMEs from SECCHI/HI observations. We apply these two models to four CMEs well observed by both STEREO spacecraft during the year 2008. We find that in… Expand
