    Why does this barred spiral appear to have two arms going in opposite directions or have formed a half circle? The upper right half shows no sign of arms. Any ideas?

    May be a partial #ring, or it may be apparent only (i.e. an artifact; the image looks noisy, so the extensive processing may have produced features that are not real)
