We discovered two transient events in the Kepler field with light curves that strongly suggest they are type II-P supernovae. Using the fast cadence of the Kepler observations we precisely estimate the rise time to maximum for KSN2011a and KSN2011d as 10.5$\pm 0.4$ and 13.3$\pm 0.4$ rest-frame days respectively. Based on fits to idealized analytic models, we find the progenitor radius of KSN2011a (280$\pm 20$ R$_\odot$) to be significantly smaller than that for KSN2011d (490$\pm 20$ R$_\odot$) ... v0.98.9 based on the original Updated 2016/03/22 10:35:11
