NGC 3347 is a two-armed spiral of the
grand design type despite the fact that the spiral
subclass is (r) because of what appears, at this
high inclination angle, to be an internal ring.
The two principal arms have high surface
brightness. They are studded with small, generally
unresolved HII regions. The redshift of NGC 3347
is v_o = 1201 km/s.
Overexposed center and bar, pretty faint (r): 0.95 x 0.4, thin patchy
arms with several bright knots. Very faint bridge to NGC 3354 3.3 south-
=ESO 376- G 13
Two principal well-developed thin and symmetrical arms
with regular dust patterns on the inside of one of the arms,
and down the center of the other.
The arms are lumpy with a large double association of
about 7 arcsec diameter.
The many evident HII regions will be difficult to resolve,
although the largest may have approximately 2 arcsec diameter.
Clearly a high-luminosity galaxy.
Non-interacting pair with NGC 3354 at 3.5 arcmin.
NGC 3358 at 8.5 arcmin
In Klemola Group No. 16 (A.J., 74, 804, 1969).
Atlas Gal. Australis, 1968.
Small, very bright nucleus. 2 stars or emission patches in the northern arm.
Non-interacting pair with NGC 3354 SB: at 3.5 arcmin (inner dimensions:
0.45 arcmin x 0.35 arcmin) and NGC 3358 at 8.5 arcmin.
