Re:[DBA2001] FA 28
FA28 This is the spiral [SA(s)c] NGC 3956 with a heliocentric radial
velocity of 1645 +/- 5 km s^-1^. It has patchy arms with many knots.

NGC 3956 is in a rich field that includes the
RSA galaxies NGC 3957 (S0_3_; panel 44), at a
separation from NGC 3956 of 59.2' with a
redshift of v_o = 1583 km/s, and NGC 3981 (Sbc;
panel 178), at a separation of 50.0' with a
redshift of v_o = 1554 km/s. The redshift of
NGC 3956 itself is v_o = 1394 km/s. If the three
galaxies are physically related with mean redshift
of = 1510 km/s at a redshift distance of
30 Mpc (H = 50), the projected linear separations
from NGC 3956 are 516 kpc and 436 kpc
from NGC 3957 and NGC 3981, respectively.
These dimensions are similar to the size of the
Local Group.
The field around and between these three
bright galaxies contains many dE, Im, and Sm
dwarf galaxy candidate members of the group.
