We use Tully–Fisher distances for a sample of field late spiral galaxies to test the Lauer and Postman ( 1994 ; hereinafter LP ) result suggestive of a bulk flow with respect to the Cosmic Microwave Background reference frame , of amplitude of +689 km s ^ { -1 } in the direction l = 343 ^ { \circ } , b = +52 ^ { \circ } .
A total of 432 galaxies are used , subdivided between two cones , of 30 ^ { \circ } semiaperture each and pointed respectively toward the apex and antapex of the LP motion .
The peculiar velocities in the two data sets are inconsistent with a bulk flow of the amplitude claimed by LP .
When combined in opposition , the peculiar velocity medians in shells of constant redshift width are never larger than half the amplitude of the LP bulk flow .
Out to 5000 km s ^ { -1 } the median bulk velocity in the LP apex–antapex cones is about 200 km s ^ { -1 } or less , dropping to a value indistinguishable from zero beyond that distance .
It can be excluded that field spiral galaxies within 8000 km s ^ { -1 } partake of a bulk flow of the amplitude and direction reported by LP .
