Re:UGC 05982
UGC 5982 (NGC 3430)
This galaxy has a strange spiral pattern, with 3 arms, seen in
visible light as well as in H{alpha}. In fact it seems that there
is a secondary western arm, parallel to the main one. Despite its
oddity this galaxy has a regular velocity field, with classical
wiggles at the crossing of the main spiral arms. Its rotation
curve is quite typical of its type, rapidly reaching a plateau
around 180 km s^-1^. Both sides are perfectly symmetric. The
rising part at the end of the curve, seen on the blueshifted side,
could be explained by the interaction with UGC 5972. The WHISP HI
data clearly suffer from a technical problem since almost no signal
was detected (see graphical overview on their Web site) whereas
Nordgren et al. (1997) have observed it with the VLA successfully
when studying its interaction with its neighbour UGC 5972. They
show that the disks of both galaxies are warped at the outer edges
and that there is a tidal tail extending from UGC 5982 towards the
NE, also they underline that the optical images show little sign
of tidal interaction.

Re:NGC 3430
NGC 3424 and NGC 3430: our Nancay profiles of these two nearby objects
(4.5' E-W separation) will be mutually confused by their line emission, as
will the published Green Bank and Jodrell Bank profiles of NGC 3430. The
Arecibo profiles (Helou et al. 1982) of the two galaxies are not expected
to be confused, given the telescope's small HPBW. The Arecibo central
velocities are 1501/1586 km s^-1^, the FWHMs 353/340 km s^-1^, and the
integrated line fluxes 14.0/44.1 Jy km s^-1^, respectively.

22. NGC 3430 is a fairly regular Sbc spiral with thin arms and with medium
inclination. The fits yielded excellent residua (Fig. 5 in on-line
version).

5.2 NGC 3424-30
Figures 3(a) and 3(b) show the optical Gunn r image of the NGC 3424-30
system. NGC 3424 is the nearly edge on galaxy to the SW of the larger, more
face on spiral, NGC 3430. The optical images show little sign of tidal
interaction, apart from a faint "spray" of optical emission visible on the NE
edge of NGC 3424's disk. The detection of faint features from near NGC 3430 is
made difficult by the bright star to the NW of the galaxy.
The Natural weighted H I contours in Fig. 3(a) show that both galaxies reside
in a common envelope (although there are clearly two kinematical centers). The
region of H I emission between the two galaxies is about four beam diameters
across. There is a bulge in the H I envelope of NGC 3424 which corresponds to
the position of the "spray" seen in Fig. 4(a). The velocity field in Figs. 3(c)
and 3(d) shows that the H I disk of both galaxies are warped at the outer
edges. The direction of the velocity gradient between NGC 3424 and NGC 3430,
coupled with the similar direction of the gradient in each disk means that both
galaxies are undergoing a direct encounter. The tidal tail extending from NGC
3430 towards the NE plus the emission extending from NGC 3424 towards the SW
are typical of such an encounter after the system has already gone through
perigalacticon. Figure 4 is the simulated single dish spectrum for the system.
Also present in this system [Figs. 3(a) and 3(c)] is the faint galaxy to the SE
of NGC 3430 which we call NGC 3430A. Seen in both the Gunn r image as
well as the H I moment maps, it is at a velocity closest to that of the west
end of NGC 3424. This object is not listed in NED.

The spiral pattern in NGC 3430 is
intermediate between the grand design and the MAS
types. The arms are thin. The high-surface-brightness
segments can each be well traced for
at least half a revolution.
The redshift is v_o = 1555 km/s.

Re:NGC 3430
NGC 3430
Our CO observations only allow us to rule out the possibility of there
being a strong line. NGC 3430 is in interaction with NGC 3424; the
distance between their centers is about 6'(36 kpc) and their velocity
difference is 100 km/s. NGC 3413 is about 10' away although at only
645 km/s and NGC 3395/3396 at less than 30'. NGC 3486 is optically bright
with strong HI but our CO detections are dubious.
