Peculiar velocities are one of the only probes of very large scale mass density fluctuations in the nearby Universe. We present new `minimal variance' bulk flow measurements based upon the `First Amendment' compilation of 245 Type Ia supernovae (SNe) peculiar velocities and find a bulk flow of 249±76 km/s in the direction l= 319°± 18°, b= 7°± 14°. The SNe bulk flow is consistent with the expectations of Λ cold dark matter (ΛCDM). However, it is also marginally consistent with the bulk flow of a larger compilation of non-SNe peculiar velocities. By comparing the SNe peculiar velocities to predictions of the IRAS Point Source Catalogue Redshift Survey (PSCz) galaxy density field, we find Ω^0.55_mσ_8,lin= 0.40±0.07, which is in agreement with ΛCDM. However, we also show that the PSCz density field fails to account for 150±43 km/s of the SNe bulk motion.
