The velocity field shows no real signs of perturbations, except for a clump in
the receding half to the South (RA ~ 12^h^17^m^12.53^s^, Dec.+15^deg^18'58"),
which exhibits a lower velocity (~900 km s^-1^) than its surroundings (~950 km
s^-1^). Streamings of gas are also observed.

The spiral pattern of NGC 4237 is similar
to that of NGC 2715, above. The reproduction
in the Hubble Atlas was made from the same
Mount Wilson 100-inch plate shown here.
The redshift of NGC 4237 is v_o = 814 km/s.
The galaxy is in the region surveyed for the
Virgo Cluster Catalog. It is located 4.5^deg^
northwest of NGC 4486, associated with Virgo
SAB(rs)bc (de Vaucouleurs)
Small, bright nucleus. Pseudo (r): 0.75 arcmin x 0.3 arcmin. Many knotty arms.
Apr. 21/22, 1938
The three galaxies shown on this bottom panel form a
subgroup of Sb similar to the NGC 0253-2903 group of Sc
(pp. 34 and 35 of the Atlas). The arms are not well
separated from each other, and they are difficult to trace.
They start at the small compact nucleus. Considerable
dust is spread throughout the fundamental plane, and the
dust arms define the spiral pattern fully as well as the
luminous arms between the dust lanes.
