Re:NGC 2442
NGC 2442: Suggested by Moiseev (2001), based on the suggestion of a triaxial
bulge by Baumgart & Peterson (1986); Jungwiert et al. (1997) list this in their
"twisted isophotes" category. Inspection of their H-band isophotes suggests
there may be a nuclear bar with a ~ 2.5-3"; higher-resolution observations are
needed for confirmation and accurate measurements. The outer bar is peculiar and
difficult to define; it is somewhat similar to those of NGC 1808 and NGC 4725.

Re:NGC 2442
NGC 2442.---SBbc: Bright nuclear point source embedded in a small,
very elliptical bulge. Outer bulge isophotes become boxy (actually
rhomboid). Spiral arms emerge from the obtuse corners of the rhombus.
Spiral arms are rich in star-forming knots. Dust lanes still visible
in the H band. The arms are asymmetric. The north arm emerges from
the east corner of the bulge, is nearly straight for some distance,
and then bifurcates, and turns sharply to the west (the bending angle
is ~120deg). The south arm is straight, with a narrow central ridge
line for even farther, and then bends sharply to the east (the bending
angle is ~150deg), and becomes quite diffuse and broad. It appears to
bend entirely back on itself at low intensity level.

Re:NGC 2442
NGC 2442 (Fig. 21), a member of the Volans Group, has an asymmetric
appearance which may be a result of tidal interaction (Mihos & Bothun
1997) or ram pressure stripping (Ryder et al. 2001). The H{alpha} image
by Mihos & Bothun (1997) shows an unresolved central source and a
circumnuclear star-forming ring of 8" (~0.6 kpc) radius. NGC 2442
exhibits strong radio emission from the nucleus and the ends of the bar.
Very strong and polarized emission has been detected in the northern arm
(hosting a massive dust lane) with aligned field lines, possibly a
signature of field compression and/or shearing. Diffuse radio emission
is visible in the eastern part (Fig. 21), with a blob of highly polarized
emission (Fig. 26). This galaxy will be discussed in Paper III
(Harnett et al. 2002).

Re:NGC 2442
NGC 2442 (SABbc, 1"~74 pc, I=27.8^deg^)
The inner isophotes are twisted inside the large-scale bar: {delta}PA~29^deg^
between a=3" and 10".

5. 1995A&AS..114..147B
Re:NGC 2442
This galaxy is a member of a small group in Volans. It has been
classified as SAB(s)bc pec in the RC3. The bar or lens appears as an
ellipse with a length of about 66". From the ends of this bar two main
arms originate which run symmetrically along the NE-SW direction for
almost 2' and with small curvature. Thereafter both arms differ much from
each other in a similar way as in NGC 1672. There seems to be present
also a weak elliptical annular structure (a sort of inner ring), with the
same orientation as the bar, with a diameter of about 3.3' and an axial
ratio of 0.5. Recently Sersic & bonzelli (1993) made photometric studies
of this galaxy.
NGC 2442 was observed also in the continuum by Harnett (1984). The map
shows that the extended emission in the continuum traces most of the
important features of the galaxy, in particular the northern arm. There
are also three peaks, one at the centre of the galaxy and the other two
at each end of the main body, at the NE and at the SW. The galaxy was
also observed in the HI line by RMGWS82 and by Bajaja & Martin (1985).

Triplet? [with NGC 2434 and NGC 2397]

NGC 2442 forms an apparent pair with
NGC 2434 (E0; panel 1) at a separation of
16.8'. The redshifts are v_o(2442) = 1157 km/s
and v_o(2434) = 1118 km/s. At the mean redshift
distance of 23 Mpc (H = 50) the projected
linear separation is 112 kpc. A possible distant
association is with NGC 2397 (Sc; panel 279) at
a separation of 85' at a redshift of v_o = 1044 km/s.
The projected linear separation would be
570 kpc if there is a common distance.
The central part of NGC 2442 is an oval
rather than a well-defined bar. Heavy dust lanes
exist, the strongest of which threads the middle
of the best-defined arm of the grand design pattern.
The largest HII region in this arm resolves
(core plus halo) at about the 5" level.

Re:NGC 2442
Dust is the dominant feature in this galaxy, in addition to its small
bulge, short bar and asymmetric arms. A lot of the confusion is due to
our viewing angle, but even that is not well determined-is it nearly
face-on, with the northern arm tightly wrapped; or more edge-on, with a
warped southern arm? Based on the geometry of its bright arms and dark
dust lanes, de Vaucouleurs (1958) favors a lower inclination i ~ 30^deg^
and argues that the southeastern side is nearest to us. H II regions are
nearly contiguous along both arms, and can also be seen at the very tips
of the arms, as well as near the bar, in what appear to be extensions
past the points where the arms intersect the bar. While dust lanes
beautifully bisect each of the two main arms, it is interesting to note
that the H II regions lie mainly on the inner edge of the northern arm,
but do the opposite in the southern arm.
The object NGC 2443 is listed as lying 1' south of the nucleus of
NGC 2442, although Sulentic & Tiffi (1973) consider it to be nonexistent.
The amorphous patch tucked just inside the southern arm, which has H II
regions associated with it, may in fact be the cause or perhaps the
result of an interaction, but more in-depth studies of the neutral gas
will be needed to address this issue.

Re:NGC 2442
Much dust throughout the inner disk.
Excellent dust lane down the center of one of the two principal arms.
Small nucleus but with an internal spiral pattern.
Probably will not resolve usefully into HII regions as the arms
are too lumpy, but there are HII regions in the arms.
Candidate for the largest region has about a 2 arcsec diameter.
H{alpha} plates may well separate the candidates
from the background arm confusion.
