We examine the light curve parameters of 97 nearby Type Ia supernovae in theultraviolet and optical using observations from the Swift Ultra-Violet/OpticalTelescope. Our light curve models used a linear combinations of templates,which were based on Functional Principal Component Analysis of the opticalphotometry of SNe Ia. The weights for each principal component used in the fitcapture certain aspects of the light curve properties. We find that there islittle difference in the overall variability of principal component scoresacross filters. We also find correlations between certain filters and PCcomponents, indicating that the UV and optical properties seem to be tiedtogether. This is a promising step in UV SNe Ia analysis, and suggests that UVlight curves may be used to infer optical properties, paving the way for futurecosmological studies.
