Re:NGC 1241
NGC 1241: Laine et al. (2002). Outer-bar measurements are from a NICMOS3
F160W image, with inner-bar measurements from a NICMOS2 F160W image; the
inner-bar a_{epsilon} is based on an extremum in the ellipse-fit PA, and
L_bar_ is from the size of the nuclear ring.

Re:NGC 1241
NGC 1241 (GD)
This is a well-defined, if inclined, example of a grand-design dust
spiral. These arms appear to fragment somewhat in the central few
hundred parsecs, although the main two arms are still visible down to
these smallest scales.

Re:NGC 1241
NGC 1241.---SB(r)ab: Nuclear point source. Bulge becomes
elliptical/boxy at lower intensity levels. Prominent bar emerges from
opposite corners of the boxy bulge. Strong two-arm pattern with arms
originating in bright ansae at the ends of the bar. North arm is much
more tightly wrapped than south arm. Several other arms appear at low
surface brightness levels. LSB disk extends farther to the NW than the
SE (disk major axis runs SE-NW). This may be due to an interaction
with a fainter peculiar late-type galaxy to the NE.

Re:NGC 1241
The color map for NGC 1241 (Fig. 2f) reveals an overall dust
morphology that is consistent with an inclined ring at the terminus of
bar dust lanes. There is a red half-ellipse close to the nucleus with a
minor axis of about 1.5" and a major axis of ~4". The other side of the
ellipse does show in extinction but at a much lower level. This ellipse
connects to red features that lead off the image to the southeast and
northwest. The overall reddening to the southwest of the nucleus is
stronger, implying that this is the near side of the galaxy.

Pair [with NGC 1242]

Racine wedge
NGC 1241 forms a close pair with NGC 1242
(Sbc; not in the RSA) at an angular separation
of 1.6'. The redshift of NGC 1242 is unknown,
but if it is nearly the same as that of NGC 1241,
v_o = 4072 km/s, the redshift distance of
the pair is 81 Mpc (H = 50) giving the small
projected linear separation of 38 kpc. However,
there is no evidence of morphological distortion
in either NGC 1241 or NGC 1242 that would be
evidence of a close encounter; the pair may be
optical rather than binary. (Redshifts are
needed.)
The two high-surface-brightness inner arms
begin at the ends of the central oval; the latter
has the properties of a bar, signaled by the two
characteristic dust lanes in the oval (bar) of
prototype SBb and SBbc types. Multiple arms
branch from the two main grand design inner
arms.

Re:NGC 1241
= Holm 068a
Part of Arp 304 = VV 334
Pair with NGC 1242 at 1.5 arcmin
NGC 1243 (= Holm 068b) at 3.1 arcmin is a double star.

Re:MCG -02-09-011
Paired with MCG -02-09-012
{rho} = 1.6 arcmin.
Photo: VV 334; Arp 304.
Interaction suspected.
This is a triple system (= Holm 068) where the third
component is associated with NGC 1243, but NGC 1243
notwithstanding, the third component of Holmberg triple
does not exist.
According to deV MCG -02-09-011 is of type SB(rs)b

8. 1964RC1...C...0000d
Re:NGC 1241
= Holm 068a
Non-interacting pair with NGC 1242 at 1.5 arcmin.
Very small, very bright nucleus.
(r): 0.7 arcmin x 0.5 arcmin,
2 main arms, weak filamentary outer arms.
