1. 1994CAG1..B...0000S
Re:NGC 5426
Pair [with NGC 5427]
Sbc(rs)I.2
CD-909-HB
April 29/30, 1979
103aO + GG385
40 min
Both NGC 5426 and NGC 5427 have normal
Sbc morphologies. They evidently form a
physical pair; the redshifts are v_o = 2455 km/s
and v_o = 2565 km/s, respectively. The angular
separation of 2.3' corresponds to a projected
linear separation of 34 kpc at the mean redshift
distance of 50 Mpc (H = 50).
The only evidence for a close tidal encounter
are the two thin straight strands of the multiple
outer arms of NGC 5426 that overlap the outer
thin spiral arms of NGC 5427, where the spiral
pattern is of the grand design. Otherwise, each
galaxy has beautifully formed arms that are so
regular that each is assigned the earliest
luminosity class because of the small geometrical
entropy. Evidently, close encounters at some
phase in their action have had nearly negligible
perturbative effects on the visible morphology.

Re:NGC 5426
= Holm 573b
Bright diffuse nucleus. Bright center. Several filamentary, knotty arms,
2 extending to NGC 5427.
Heidelberg Veroff. Vol. 9, 1926 minor-axis dimension (0.7 arcmin) is much
too small.
H.A. 88,2 dimensions (after Helwan) are for the bright part only.
(B-V) source E rejected.
Interacting pair with NGC 5427 at 2.3 arcmin (NGC 5426 is the southern
component)
