We present an analysis of the rise-time distribution of nearby (z< 0.05) Type Ia supernovae (SNe Ia). Drawing mostly from the recently published Lick Observatory Supernova Search (LOSS) SN Ia sample along with other published nearby SNe Ia with data starting at least ten days before maximum brightness, we use a two-stretch template-fitting method to measure the rise and decline of light curves compared to a fiducial template. We find a correlation between the decline and rise of the light curve in the sense that SNe with slow decline rates have longer rise-times. A comparison of the rise-time distribution of spectroscopically normal SNe Ia to SNe Ia with high-velocity spectral features indicates possible differences in their parent distributions. We gratefully acknowledge the financial support of NSF grant AST-09088886 and the TABASGO Foundation.
