Re:NGC 1617
NGC 1617.---(R)SAB0/a (type example---see Fig. 3b): Bright nuclear
point source. Extends into slightly elliptical bulge. Weak bar. Stubby
spiral features emerge from the bulge but quickly fade into the
overall disk emission. Disk is slightly asymmetric: The major axis
P.A. is roughly 100deg east of north; the disk is slightly less
extended to the north than to the south. Disk is very smooth, with no
evidence of star-forming knots. Disk terminates abruptly at an outer

The inner spiral pattern in NGC 1617 is
defined almost entirely by fragmentary dust arms
pervading the high-surface-brightness disk. A
smooth, almost spherical bulge exists at the
center of the disk, burned out in this print. The
arms, which become luminous in the outer
regions, are tightly wound, nearly overlapping
the next inner-arm system after a half revolution.
The pattern is similar to that in the galaxies on
panels 69 and 78.
Very few if any HII candidate knots exist in
the arms, indicating a lack of appreciable recent
star formation.

The internal lanes in NGC 1617 that are the
inner spiral arms are well seen in the positive
print on panel 79, where the multiple-armed
spiral pattern is evident. The outer pattern of
moderately smooth luminous arms shows here
and on panel 79 as tightly wound fragments.
NGC 1617 is later along the MAS Sa sequence
than NGC 3385 but is earlier than NGC 4698
below. It is much earlier than NGC 4699 and
NGC 2775 in the right-hand column.

Re:NGC 1617
Plate 1893
Overexposed bar, smooth arms form (R'): 3.1 x 1.3. Similar to NGC 4826.

5. 1979AJ.....84..472S
Re:NGC 1617
Very early Sa.
Much dust in high-surface-brightness disk
that is well organized into a spiral pattern.

M.N.R.A.S., 131, 351, 1966.
Atlas Gal. Australis, 1968.

Re:NGC 1617
Very bright nucleus.
Bar: 1.8 arcmin.
Poorly resolved.

8. 1957HPh....53..275d
Re:NGC 1617
(Plate 10)
Very small nucleus in short and fainter bar, curving into spiral
arms in lens and envelope.
The spiral pattern is blurred by insufficient resolution here.
Compare with NGC 7079 (Plate 9) and NGC 1512 (Plate 14).
