An asymmetric barred spiral. The emission originates largely in the
arms, but the continuum of the nucleus is blue. In the SW arm
([O III]) > ([O II]), but in the nucleus ([O II]) > ([O III]).
Note correction to NGC R.A.
One arm leaves normal to the nucleus, and the other one is brighter
and tangent to the nucleus and turns into a spiral arm.
