We have obtained deep FUV, NUV, and Hα imaging of a small sample of nearby spiral galaxies in order to study the recent massive star formation in the outer disk. We have identified 20-60 individual star forming regions outside of R25 for most of the galaxies in our sample. Similar to other studies, we find a large amount of scatter between the UV colors of individual star forming regions in the outer disks. We are able to reproduce the observed range of FUV-NUV colors using GALAXEV models with episodic sampling of exponentially declining star formation rates. We compare results for both the inner and outer disk; we find that the time between star formation episodes combined with the ratio of current to past star formation rate has a pronounced effect on the predicted range of FUV-NUV color.
