De Vaucouleurs Atlas Description:
This face-on galaxy includes a strong bar and a very well-defined inner pseudoring of the wrapped arm type. The ring is formed from two arms which break from opposite ends of the bar. The inner pseudoring fades quickly outside the bar region. At about twice the inner pseudoring radius, a large, well-defined outer ring is found. This ring also appears made partly of spiral structure, and includes considerable patchiness on one side. A B-V color index map (not shown) indicates recent star formation in this region (see also Ryder and Dopita 1993). Weak dust structures are found in the bar and inner pseudoring area. Recent star formation is largely confined to the outer ring .
Bettoni et al. (1990) detected peculiar ionized gas kinematics in the inner 1 kpc of NGC 2217 . Bettoni et al. (2001) attribute an apparent counter-rotation to a warped inner disk, i.e., a projected view of a series of polar rings in this region. Jungwiert et al. (1997) also identified a secondary bar in this region. This feature is visible in the Atlas image as a small inner oval.
