Re:UGC 06419
UGC 6419 (NGC 3664, Arp 05). It is one of the prototypical strongly barred
magellanic spirals and has a nearby companion, UGC 6418, at 6.2 arcmin. H I Very
Large Array (VLA) observations (Wilcots & Prescott 2004) show that the current
interactions affect the morphology and the kinematics of the main galaxy. The H
I velocity fields of both galaxies are connected, with a large extension (~10
arcmin) compared with the optical one (~1 arcmin). The PA of the major-axis of
our H{alpha} velocity field is almost perpendicular to the H I one. Indeed, the
gradient of our H{alpha} velocity field is almost aligned along the bar, which
cannot be seen in the H I data due to the low spatial resolution. It is
therefore possible that our H{alpha} rotation curve does not reflect the
rotation of the galaxy but more probably the kinematics of the bar, likely to be
affected by non-circular motions. Anyway, the shape of our rotation curve (solid
body type) is not surprising for a galaxy of this type, but we find a rather low
r otation velocity considering the luminosity of that galaxy. This suggests that
the kinematical inclination (66^deg^) as well as the inclination determined from
the disc shape when excluding the tidal tail (57^deg^) are too high. Indeed, the
axial ratio of the disc including the tidal tail is close to one, suggesting
that the galaxy is seen almost face-on. We conclude that the velocities of our
H{alpha} rotation curve are probably underestimated. Furthermore, the H I
velocity field amplitude observed by Wilcots & Prescott (2004) (~150 km s^-1^)
is about twice ours (~70 km s^-1^), suggesting that we do not reach the maximum
of the rotation velocity.

Re:UGC 06419
The FSC and NVSS identifications are correct despite the large
FSC/optical and NVSS/optical offsets for this irregular galaxy.

Re:NGC 3664
Pair [with NGC 3664A]

Many HII-region candidates exist in the bar
of the disturbed morphology of NGC 3664. A
smaller companion (NGC 3664A; type SBm) with
the same disturbed morphology and the same
high degree of resolution into HII-region
candidates exists at a separation of 6.3'. The
redshift of NGC 3664 is v_o = 1231 km/s. If, as
seems likely, the two galaxies form a pair at the
same redshift distance of 25 Mpc, their projected
linear separation is small at 46 kpc. This, and
their disturbed morphology, suggest that a close
encounter may have occurred.
None of the many HII-region candidates are
resolved at the 1" level.

MCG +01-29-041 = VV 251 = Arp 005 = NGC 3664; 13.6m.
Similar here are VV 140, VV 524, VV 242, and VV 525; straight but
disrupting formations. V_0_=+1253 (RC1) bright [O II], [O III] and
hydrogen lines, inclined. Here is a nest of one larger, several
ireegulars in contact and many dwarfs, of which 5 form a chain.
