Context : Our Local Group of galaxies appears to be moving relative to the Cosmic Microwave Background with the source of the peculiar motion still uncertain .
While in the past this has been studied mostly using galaxies as distance indicators , the weight of type Ia supernovae ( SNe Ia ) has increased recently with the continuously improving statistics of available low-redshift supernovae .

Aims : We measured the bulk flow in the nearby universe ( 0.015 < z < 0.1 ) using 117 SNe Ia observed by the Nearby Supernova Factory , as well as the Union2 compilation of SN Ia data already in the literature .

Methods : The bulk flow velocity was determined from SN data binned in redshift shells by including a coherent motion ( dipole ) in a cosmological fit .
Additionally , a method of spatially smoothing the Hubble residuals was used to verify the results of the dipole fit .
To constrain the location and mass of a potential mass concentration ( e.g .
the Shapley Supercluster ) responsible for the peculiar motion , we fit a Hubble law modified by adding an additional mass concentration .

Results : The analysis shows a bulk flow consistent with the direction of the CMB dipole up to z \sim 0.06 , thereby doubling the volume over which conventional distance measures have sensitivity to a bulk flow .
We see no significant turnover behind the center of the Shapley Supercluster .
A simple attractor model in the proximity of the Shapley Supercluster is only marginally consistent with our data , suggesting the need for another , more distant , source .
In the redshift shell 0.06 < z < 0.1 , we constrain the bulk flow velocity to \leq 240 km s ^ { -1 } ( 68 % confidence level ) for the direction of the CMB dipole , in contradiction to recent claims of the existence of a large amplitude dark flow .

Conclusions :
