NGC 5464 and NGC 178, below, are similar.
Both have small angular diameters, high
surface brightness, HII-region candidates, spiral
patterns that are difficult to trace, and bright
absolute magnitudes for the SBm morphology.
The redshift of NGC 5464 is v_o = 2455 km/s.
The largest HII-region candidate appears to
resolve at the 2" level, corresponding to a linear
diameter of about 475 psc. The absolute magnitude,
corresponding to the apparent magnitude of
B_T_ = 13.2, is bright, at M_B_ = -20.6.
