NGC 4933 is a clear case of interaction,
with consequent distortion of the dust disk in the
brighter member and an evident tidal plume to
the right of the E2 galaxy. The projected angular
separation of the two main galaxies is 0.9'. The
fainter Scd galaxy in the field to the left of NGC
4933 is separated by 2.5'. There is no indication
that this galaxy is physically connected with the
The redshift of NGC 4933, corrected to the
centroid of the Local Group, is v_o = 3070 km/s.
The projected linear separation of NGC 4933
from its E2 companion is small at 16 kpc,
suggesting that this is indeed an encounter.
The most obvious unusual feature is the
warped dust disk, similar to that in NGC 3190
(Sa; panel 76), which presumably has also been
warped by an encounter.
