1. 1994CAG1..B...0000S
Re:NGC 5660
Pair? [with NGC 5676]
Sc(s)I.2
PH-7864-S
Sep 5/6, 1980
103aO
12 min
NGC 5660 may form a wide pair with NGC 5676
(Sc; panel 245) at a separation of 30.5'. It
also has a likely dwarf ImIII companion of
unknown redshift at the small separation of 2.6'.
The redshifts are v_o(5660) = 2433 km/s and
v_o(5676) = 2239 km/s. At the redshift distance
of 47 Mpc (H = 50) the projected linear separations
are 417 kpc for NGC 5676 and 35 kpc for
the ImIII companion.
The spiral pattern in NGC 5660 is
prototype Sc(s) of the grand design type where
the two main arms begin at the center.
