History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 5469 may be CGCG 074-136. [There has been considerable confusion about this object, so I'm scratching my original note and starting over.] Tempel does not list this object in his table of novae in his 8th list, but instead describes it in the text. Here is the full account, translated by Wolfgang Steinicke:

"III 59 [= NGC 5482] is 9s preceeding, 2 1/2' south of a faint star 11m; the nebula is small and has in its center a faint star with very little nebular matter. Following the star 11m, there is at 15s, parallel to it [the star or N5482?] a nice round nebula, III, without a faint star [in the center]. This nebula is also new."

Tempel's text seems to suggest that his new nebula follows the 11th magnitude star by 15 seconds, but Wolfgang questions this, suggesting that it may be NGC 5482 which is on the parallel. There is, in any case, no group of two galaxies and a star in the area of NGC 5482 that could possibly match Tempel's description. He has certainly misidentified NGC 5482.

Nor is there anything at the NGC position for N5469 (the position probably comes from one of Tempel's letters to Dreyer). Furthermore, NGC 5482 (which is CGCG 074-115; WH's position is too close to that galaxy for any doubt) is another 2.5 minutes of time on east, and half a degree south. So, it cannot be the nebula that Tempel observed: the NGC position is at odds with Tempel's text.

Given Tempel's confusion in this area (see e.g. NGC 5562, also well off the nominal position), I suspect that he mistook CGCG 074-134 as NGC 5482. It has a star of about the right magnitude, 7.7 seconds following and 3.6 arcmin north, not unreasonably far off Tempel's estimates of 9 sec and 2.5 arcmin. CGCG 074-136 is 17.1 sec following CGCG 074-134, and 50 arcsec south, again not unreasonably off Tempel's description of the nova being 15 seconds following and on the parallel.

I'm not convinced that this is the correct solution, but there is nothing else in the area that comes as close to matching. So, for now, I'm putting NGC 5469 on CGCG 074-136 with a question mark.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 15.5 mag galaxy. Their coded description reads SLEL,LBM,COM1'P2F3N.
