A set of coronal field configurations was initially generated from extrapolations of the photospheric magnetic field observed by the Michelson Doppler Imager (MDI) on \\emph{SOHO}. Using an EUV intensity-based cost function, the extrapolated field lines that were most consistent with 171\\AA\\ passband images from the Extreme UltraViolet Imager (EUVI) on \\emph{STEREO} were identified.
