NGC 3513.---SBc: Flattened nuclear source embedded in a thin, HSB bar.
Broad ansae at the ends of the bar have a P.A. slightly skewed from
that of the bar. The spiral arms emerge from the ansae. The arms are
broad, and patchy, but well defined. They contain several obvious
knots of star formation. The arms can be followed through ~180deg.
They are not quite symmetric, with the south arm being more open than
the north arm, and the north arm showing signs of more vigorous star

NGC 3513 has a similar morphology to
NGC 1559 at the upper left.
The galaxy forms a close physical pair with
NGC 3511 (Sc; panel 273) at a separation of
10.5'. The redshifts are v_o(3511) = 951 km/s
and v_o(3513) = 845 km/s. At the mean redshift
distance of 18 Mpc (H = 50) the projected linear
separation is small, at 55 kpc.
The brightest part of the stellar content in
NGC 3513 resolves well. The brightest stars
individually begin to resolve at about B = 21.5.
The largest of the numerous HII regions resolve
into disks at the 2" level.
Overexposed bar, very bright patchy arms with several bright knots.
Optical pair with NGC 3511 10.5 north-preceding.

Extremely bright, small nucleus. Strong bar: 0.5 arcmin x 0.06 arcmin.
Pseudo (r): 0.85 arcmin x - . 2 main massive, knotty arms. Very faint
extensions form pseudo (R): 2.4 arcmin x 1.5 arcmin.
Non-interacting pair with NGC 3511 at 10.8 arcmin.
Helwan 21, 22, and Lund 7 dimensions are for the bright part only.
