Cosmological theories suggest that the angular momentum of galaxies is closely linked to the structure of the cosmic web. The Local Supercluster is the closest and most frequently studied structure in which the orientation of galaxy spins can be studied. As noted previously, the use of edge-on galaxies greatly simplifies this task by reducing the task to an analysis of the position angle distribution in the supergalactic coordinates. We reexamined this correlation using modern catalogs that allowed us to perform a more robust statistical analysis. We tested the dependence on redshift, spatial position, luminosity, and color. We find that the spins of galaxies with a stellar mass M_* < 10^8.7 M_⊙ show a weak tendency to be aligned perpendicular to the plane of the Local Supercluster at the 2σ level. Other subsamples show no statistically significant correlations.
