Corwin's Notes
=====
NGC 5122 has faint plumes perpendicular to the major axis of the galaxy and
aligned with the nucleus. On the IIIa-J plate for DSS2, the plumes extend to
about three times the length of the major axis, roughly 3.5 arcmin from end to
end (the major axis is about 1.1 arcmin). A popular interpretation of this is
as a "polar-ring galaxy" where an outer ring is generally perpendicular to the
disk of the galaxy. See Whitmore et al, AJ 100, 1489, 1990 for more on these
peculiar objects.
Also see IC 884.
Steve's Notes
=====
NGC 5122
18" (5/29/05): fairly faint, very small, elongated 2:1 WNW-ESE, 0.4'x0.2'. Contains a sharp, stellar nucleus or a faint star is superimposed. Confusing the situation is a similar mag 14 star that is just off the WNW extension and in line with the major axis of the galaxy. Located 35' NNW of Spica. NGC 5130 lies 27' N.
This is an edge-on polar-ring galaxy with extremely faint extensions perpendicular (SW-NE) to the major axis of the main body.
