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(-1) in the direction l = 319 degrees +/- 18 degrees, b = 7 degrees +/- 14 degrees. The SNe bulk flow is consistent with the expectations of Lambda cold dark matter (Lambda CDM). 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 Omega(0.55)(m) sigma(8,lin) = 0.40 +/- 0.07, which is in agreement with Lambda CDM. However, we also show that the PSCz density field fails to account for 150 +/- 43 km s(-1) of the SNe bulk motion.en-USJournal Article2019-09-2610.1111/j.1365-2966.2011.20050.x
