NGC/IC Project Restoration Effort

===== NGC 5469 may be UGC 9084,N1 = CGCG 074-136. [There has been considerable confusion about this object, so I've deleted my original note and started 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, kindly 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 of the NGC position for NGC 5469. 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 UGC 9084 = 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 east of UGC 9084 (and appears in the UGC note for the larger galaxy) and 50 arcsec south, again not unreasonably off Tempel's description of the nova being 15 seconds following and on the parallel -- assuming, of course, that he is indeed writing of the galaxy and not the star to the north. I'm not wholly 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. (The star with the double query is the only object near the position given in the NGC that Tempel could have reasonably seen.) Looking again at the field in August 2015, I've changed the question mark to a colon. Tempel's narrative matches too closely what we see on the sky with the two UGC/CGCG objects. This would also mean that UGC 9084 was seen before the NGC was published, so I've put it into the "notngc" files.

===== NGC 5469 18" (6/30/11): faint, very small, irregularly round, 18" diameter, weak concentration. A small right triangle of mag 13-14 stars [sides 1.1', 1.4', 2'] is close SW. Brighter of a pair with UGC 9084 4.3' WNW. The identification NGC 5469 = CGCG 74-136 is uncertain but if UGC 9084 was assumed by Tempel to be NGC 5482, then his NGC 5469 refers to CGCG 74-136. CGCG 74-141 and -142 lie ~9' ESE. See notes for NGC 5511, which may be CGCG 74-141. 17.5" (6/8/02): faint, very small, round, 15" diameter. Just following a small triangle of mag 13-14 stars. Forms a pair with UGC 9084 4.3' WNW. NGC 5511 lies 10' ESE (all three faint galaxies collinear).
