The SNAP telescope will rely on a set of stable standard stars within its deep survey to provide relative spectrophotometric calibration in the SNAP filter set. We have conducted a variability survey for such calibration stars within the SNAP North Field using the WIYN 0.9m telescope. Our goal was to discover stars with R-band magnitudes between 16-18 that are variable by less than 0.01 mag. This was accomplished through co-addition of frames and controlling systematics through differential ensemble photometry. Several systematic error issues are considered including large-scale flat fielding error and consitency within differential aperture photometry. We have compiled a list of candidate stable calibration stars and plan spectroscopic confirmation as well as continued monitoring of the SNAP field.
