CF4 data yield a 3.3σ excess dipole in the local expansion-rate fluctuation field at (l,b)=(290°,-4°)±5°, sourced mainly by z∈[0.03,0.05], with quadrupole/octupole consistent with ΛCDM and no multipole-vector alignments.

New SBF distance data confirm a steradian-scale flow converging at ~70 Mpc that matches the direction and amplitude of the CMB dipole and the original Great Attractor model.
For an observer with peculiar motion, the cosmic redshift-drift signal gains a dipolar correction proportional to the flow's projected expansion, shear, and acceleration; calibrated to CF4, it is subdominant and cannot mimic an accelerating EdS universe.
The 1+3 covariant formalism reproduces the standard result for peculiar velocity growth in cosmology and does not imply anomalous bulk flows or apparent acceleration.

Multipolar structure of the local expansion rate from incomplete sky data

Expected redshift drift for tilted observers
For an observer with peculiar motion, the cosmic redshift-drift signal gains a dipolar correction proportional to the flow's projected expansion, shear, and acceleration; calibrated to CF4, it is subdominant and cannot mimic an accelerating EdS universe.
