The bar and the region of each arm just
beyond the ends of the bar contain many HII-region
candidates. The disk is covered with very
broad, massive, ill-defined arms nearly devoid of
HII regions. The arms are not symmetrical about
the bar; one side sweeps out more widely than the
other, but there is no evidence for tidal interaction
by a companion. NGC 1536 is isolated; its
redshift is v_o = 1168 km/s.
Bright bar, broad asymmetric arms, few knots.
=ESO 157-IG 05

Very small, bright nucleus.
