Summary description: cF, pL, R, vlbM
NGC 5238, similar to NGC 5237, is in the M 101 group. It is either a double
interacting system, or a late-type irregular, well-resolved in the SDSS image.
The position for the northern component is for an eccentric blue stellar knot.
Spectra show this to be a star-forming region in the galaxy rather than a
superposed Galactic star. The position of the southern component is similarly
characterized by a blue knot. This one, however, is more diffuse and
obviously a part of the galaxy. Curiously, it has no entry in the automated
catalogs, though SDSS has picked up three of the fainter knots around it.
I've adopted a mean of those three positions.
17.5" (5/11/02): very faint, moderately large, slightly elongated ~N-S, 1.2'x1.0', very diffuse with no noticeable central concentration. NGC 5225 lies 15' SW. Possible outlying member of the M101 group.
