Observing Notes

Harold Corwin

There is no problem with the identity of this big, lovely, southern spiral. But it sits in front of a background group, one of which is a large elliptical ("IC 4721A") just a couple of arcmin to the southwest (this has been mistaken at the eyepiece at least once for IC 4721; see Corwin and Emerson, MNRAS 200, 621, 1982). There is another galaxy behind the western side of the galaxy -- in the optical, the object looks something like a peculiar arm segment of the larger, foreground spiral. But in the IR, the nucleus is actually brighter than that of IC 4721 itself. An interesting field.
