Corwin's Notes

===== NGC 6668 = NGC 6667 (as well as NGC 6678, which see). Found by Swift (included in his 4th list), this is most likely to be NGC 6667 as there is nothing at Swift's place resembling a "pB, pS, vE" nebula. Howe could not find it, either, and suggested that N6668 might be N6677. However, N6667 is brighter and its inner regions perhaps fit Swift's description better. Also, the difference in position is exactly 50 arcmin, suggesting a transcription error or a typo somewhere in Swift's reduction/publication chain. The galaxy itself looks like an S0, distorted and with a dust lane and other dust features, as well as a very extended, distorted arm reaching well out to the northwest. The modern position I've adopted comes from two 2MASS point sources in the dust lane, perhaps bracketing a hidden nucleus. Or perhaps one of the PSC sources is the nucleus. This is an unusual galaxy.
