To accurately predict the space weather effects of coronal mass ejection(CME) impacts at Earth one must know if and when a CME will impact Earth, andthe CME parameters upon impact. Kay et al. (2015b) presents Forecasting a CME'sAltered Trajectory (ForeCAT), a model for CME deflections based on the magneticforces from the background solar magnetic field. Knowing the deflection androtation of a CME enables prediction of Earth impacts, and the CME orientationupon impact. We first reconstruct the positions of the 2008 April 10 and the2012 July 12 CMEs from the observations. The first of these CMEs exhibitssignificant deflection and rotation (34 degrees deflection and 58 degreesrotation), while the second shows almost no deflection or rotation (<3 degreeseach). Using ForeCAT, we explore a range of initial parameters, such as the CMElocation and size, and find parameters that can successfully reproduce thebehavior for each CME. Additionally, since the deflection depends strongly onthe behavior of a CME in the low corona (Kay et al. (2015a, 2015b)), we areable to constrain the expansion and propagation of these CMEs in the lowcorona.
