Corwin's Notes

===== NGC 5318. Steve Gottlieb notes an observation in WH's Sweep 407 on 3 May 1785 that reads "Suspected, vF, i, and vS, but 240 made it appear more like a small patch." WH's position (13 50 42, +33 42.6; J2000, re-reduced from his offsets from AW CVn = HD 120933) lands just a few seconds east of NGC 5318, the brightest galaxy in the group, so his position likely refers to this galaxy. However, he did not make -- or chose to ignore -- the connection between the two observations, so this later one was apparently deliberately skipped during the assembly of his catalogue. Steve also notes that Mitchell found two companions ("patches"!) near this galaxy. See the entry in the "notngc" files for that story. See NGC 5312 and 5319 for more on this group.

Steve's Notes

===== NGC 5318 48" (4/15/10): bright, fairly large, oval 2:1 NNW-SSE, 1.0'x0.5', bright core, stellar nucleus, high surface brightness. This galaxy is the brightest in a group with 7 galaxies picked up in the 510x field (6 in a 10' string oriented NNW to SSE). The closest two companions, MCG +06-30-097 and MCG +06-30-095 (incorrectly identified as NGC 5319 in several sources), are located 52" NNW and 1.9' NNW, respectively. These two companions were described and sketched using Lord Rosse's 72", but did not receive NGC numbers. 18" (5/16/09): moderately bright, moderately large, elongated 3:2 ~N-S, 0.8'x0.5', bright core. Brightest of 4 NGC galaxies with NGC 5321 4.6' SSE, NGC 5312 11' SW and NGC 5319 3.5' NNE. 17.5" (5/22/93): moderately bright, fairly small, round, prominent core, stellar nucleus. Forms a pair with NGC 5321 4' S. NGC 5312 lies 10' SW.
