We use the recently completed redshift-distance survey of nearby early-typegalaxies (ENEAR) to measure the dipole component of the peculiar velocity fieldto a depth of cz ~ 6000 km/s. The sample consists of 1145 galaxies brighterthan m_B=14.5 and cz < 7000 km/s, uniformly distributed over the whole sky, and129 fainter cluster galaxies within the same volume. Most of the Dn-sigmadistances were obtained from new spectroscopic and photometric observationsconducted by this project, ensuring the homogeneity of the data over the wholesky. These 1274 galaxies are objectively assigned to 696 objects -- 282groups/clusters and 414 isolated galaxies. We find that within a volume ofradius ~ 6000 km/s, the best-fitting bulk flow has an amplitude of |vbulk| =220+/- 42 km/s in the CMB restframe, pointing towards l=304 +/- 16 degrees, b=25+/- 11 degrees. The error in the amplitude includes statistical, sampling andpossible systematic errors. This solution is in excellent agreement with thatobtained by the SFI Tully-Fisher survey. Our results suggest that most of themotion of the Local Group is due to fluctuations within 6000 km/s, in contrastto recent claims of large amplitude bulk motions on larger scales.Comment: 11 pages, 2 figures, ApJL, accepted (updated results; matches  accepted version
