Is the name "Northern" Jewel Box reliable?
I am surprised by the informal name "Northern Jewel Box" for the open cluster NGC 6231. The object is at approximately 42 degrees South. On the other hand, I guess the Jewel Box cluster (NGC 4755) is at 60 degrees South, so NGC 6231 does happen to be a bit further north than NGC 4755. Although a Google search does occasionally show sources mentioning the name "Northern Jewel Box" for NGC 6231, most of these are mentions in passing and none of them seem particularly authoritative. It's also not clear to me whether this is a case of citogenesis.

If this name is to be used, I'd like to find a reference to the origin/explanation for this name, or at least an authoritative source.

FYI, Simbad does not list a common name for NGC 6231, unlike the cluster NGC 4755 for which "Herschel's Jewel Box" is included as one of the identifiers. OtterAM (talk) 17:48, 5 August 2019 (UTC)

There is precedent for north and south to simply be relative terms and not representative of it equatorial coordinates, for example: zubenelgenubi and zubeneschamali are right next to each other and are derived from 'northern claw' and 'southern claw'.

Since 'Northern Jewel Box' is an informal name, it will by definition have informal origins. I came to know it by this name by word of mouth and noticed its absence when looking up the cluster here on wikipedia a month or so ago. At the time I added it I checked for instances of the name's use and here is what I found:

- 1,001 Celestial Wonders to See Before You Die by Michel E. Bakich published in 2010 by Springer

- A Journey through the Universe: Gresham Lectures on Astronomy by Ian Morrison refers to the "Nothern Jewel Box" in Scorpius, but does not give its NGC or Caldwell designations published in 2014 by Cambridge University Press

 * OK. I kept your changes, although if better references can be found, they would be useful. I also did some reorganization to make the article more encyclopedia like. I moved the paragraphs about the common names and history to their own sections. I also added a link to the Cadwell catalog to the info bar on the right. OtterAM (talk) 20:27, 5 August 2019 (UTC)
