NGC 5067 (13h 18.4m -10° 08') Discovered by Marth. Reinmuth lists a double star 15.5 and 16 conn 45°; neb?, very doubtful; *14 n 1.1'. See notes on N5066. Carlson follows Reinmuth and identifies as a double star. NGC 5110 (13h 22.5m -13° 05') Harold Corwin says that N5110 is identical to N5111 in ESGC but Malcolm Thompson feels the RNGC identification is a reasonable match with Swift's position at 13 22.8 -13 00 (2000). Not in MCG, RC3, ESGC. NGC 5113 (13h 21.4m +57° 42') Discovered by WH (III 808) with a poor declination. In Dreyer's 1912 revision of WH's catalogues, he comments on III 808: "Is no doubt identical with II 826 [N5113], both observed once only and in different sweeps. Carlson repeats this equivalence and Harold Corwin concludes that WH's N5113 is probably a duplicate observation of N5109 (similar descriptions). Malcolm Thompson has a long discussion of II 808 and II 826 in his Catalogue Corrections monograph and he concludes that II 808 = h1588 = N5109 = U08393 = M+10-19-061 and II 826 = N5113 = M+10-19-064 = CGCG 294-034. The latter gx is not listed in RC3 but is mentioned in the UGC notes to N5109. MCG (+10-19-064) gives the NGC designation as uncertain. NGC 5162 (13h 29.2m +11° 17') Discovered by Swift (VI). His position 13 28 17 +11 01 23 (2000) is 15' S of U08472 located at GSC coordinates 13 29 13.6 +11 16 33 (J2000). RNGC and RC3 identify this gx as N5162. Due to large discrepancy in dec, Malcolm Thompson feels this object is more likely nonexistent. This gx is not identified as N5162 in UGC (08472) or CGCG (072-084) and not listed in MCG. There is also a mag 13.3/14.7 pair with the faint star to the NE near Swift's position which also matches his visual description. So, the correct ID is very uncertain. NGC 5212 (13h 32.9m +07° 17') Discovered by JH (h 1631) and placed at 13 33 22.6 +07 17 39 (2000). (R)N5212 = CGCG 045-008 is located 1.7' SE of N5208 at GSC position 13 32 32.3 +07 17 39. This gx is not in MCG. Assuming this ID is correct, h's RA is 50s too large. h also observed h1627 = N5208 on the same sweep (253) and h1631 = N5212 was placed 56s E and 1.5' S. Interestingly there is a pair of mag 15 stars at 20" separation following N5208 by 53s and 18" S! The mean GSC position for the pair is 13 33 21 +07 18.7. Malcolm Thompson feels the RNGC identification is incorrect but a better candidate is CGCG 045-014 located at 13 32 56.0 +07 17 13. This would require only a 30s error in RA and matches in dec. Reinmuth also identifies this gx as N5212. NGC 5446 (14h 05.1m +09° 37') Discovered by WH (III 57). His position of 14 04 21 +09 38 (2000) is 1.0 tmin W of CGCG 074-093 (matches in dec). Not found by Bigourdan . This gx is not identified as N5446 in CGCG and not listed in MCG or RC3. DSS approximate position 14 05 20 +09 38.2 (J2000). Interestingly, H's RA is also just 33s E of Tempel's N5438 = M+02-36-029 = CGCG 074-075. This gx is a closer match in position and a brighter gx! So, it is possible that N5446 = N5438. NGC 5450 (14h 02.5m +54° 14') Discovered by LdR as one of numerous "knots" in M101. Listed as T7 in RNGC. The NGC position is 14 02 32 +54 13 35 which which is just 30" from a mag 14.7 GSC star at 14 02 31 +54 14 03, so the ID is uncertain. NGC 5469 (14h 02.8m +09° 20') This object was discovered by Tempel in the N5416 group and described in his list VIII (AN 2527). This is a confusing situation because Tempel's observation appears to place this object 24s of RA following N5482 although Dreyer misinterpreted his description as following N5463. So the NGC position is incorrect. The RNGC has misidentified N5469 as CGCG 074-062 = M+02-36-018. This galaxy is a close companion of N5423 and is roughly 90' from Tempel's position. Harold Corwin has suggested that N5469 may be either CGCG 074-121 or CGCG 074-122 which both follow N5482, although neither of these galaxies is a perfect fit. See RNGC Corrections #3. NGC 5558 (14h 19.1m +07° 02') Discovered by Swift (I) along with N5564 and N5565. There is only one gx in the area (N5563 from Marth). Listed as nonexistent in RNGC. Harold Corwin suggests that N5558 is a duplicate of N5552 and N5564 is a duplicate of N5554. NGC 5564 (14h 19.3m +07° 01') Discovered by Swift (I). Reinmuth claims N5564 is 1.1' SSE of N5563. I have a mag 13 star at this position in my visual observation. In the NGC, Dreyer mentions that N5564 and N5565 are probably = m279 = N5563. Listed as nonexistent in RNGC. Harold Corwin suggests that N5564 is possibly a duplicate of N5554. NGC 5565 (14h 19.3m +07° 00') Discovered by Swift (I) along with N5558 and N5564. It is possible that one of these three numbers refers to Marth's N5563 (noted by Dreyer in NGC). Listed as nonexistent in RNGC. If N5564 is a duplicate of N5558, then Harold Corwin suggests that N5565 may be the mag 15.5 star 1.8' SE of N5558 at GSC position 14 19 18.6 +06 59 42 (J2000). NGC 5580 (14h 21.6m +35° 12') Discovered by JH (h1785). Not found by Bigourdan and there is no gx at JH's position 2.5' ENE of N5579. Harold Corwin suggests that JH's N5580 may be a duplicate observation of N5590. The RNGC incorrectly identifies N5580 with an anonymous gx located 1' S of N5579. Listed in RNGC Corrections #1. NGC 5588 (14h 21.4m +35° 16') Discovered by JH (h1789). HC notes that N5588 was picked up in a sweep with N5590 but N5589 was not seen during that sweep. Furthermore, JH placed N5588 about as far S of N5590 as N5589 is N and RA's are identical, so he may have reversed the declination offsets from N5590. Malcolm Thompson also notes that it is possible that JH was mistaking a single star (which lies close NE a double star) at JH's separation values. NGC 5620 (14h 22.5m +69° 34') Discovered by WH (III 319). Described as "eF. Not verified." No object is visible on the POSS at either position mentioned in the NGC Notes section. The RNGC incorrectly identifies N5620 = CGCG 337-010 which is at least 2 deg off in dec. Not found by Bigourdan. Reinmuth describes an object as "eF, vS, iR, diffic." There is an eF gx on the DSS at roughly 14 21.5 +71 36 which is very close to the NGC (and Reinmuth's) position but is not any modern catalogue. NGC 5673 (14h 31.5m +49° 58') Discovered by JH (h1838) although incorrectly attributed to WH by Dreyer. H's offset for II 696 from 24 Boo points to the brighter SE gx which was later rediscovered by Bigourdan as IC 1029. JH assumed there was only gx here and used the place of the fainter edge-on gx 10' WNW. In Scientific Papers, Dreyer wrongly assumed that H's position was incorrect: "the transit must have been entered 1 tmin too late". Because of the error in the NGC position, this created a confusion with Bigourdan who identified IC 1029 as II 696. Harold Corwin argues letting the identifications in the major catalogues stand as JH's position was used in the GC and NGC. So, NGC 5673 = h1838 = U09347 and IC 1029 = H II 696 = B 185 = U09361. But, Malcolm Thompson feels that WH should receive credit for N5673 = I1029 although in this case the fainter gx does not receive either a NGC or IC designation). NGC 5724 (14h 39.0m +46° 42') Discovered at Birr Castle. Not found by Bigourdan. Reinmuth says "nf vnr of N5723, eeeF, vS, v diffic; identification doubtful." Identified by Harold Corwin at 14 39 02.0 +46 41 32 (2000). (R)N5724 probably refers to an anon gx with GSC position 14 39 08.4 +46 44 49 (2000) about 4' NE of the trapezium formed by N5721, N5722, N5723 and N5724. Also the MCG identification (M+08-27-016) is unclear and may refer to the correct object or an anonymous gx about 2' ENE of (R)N5724. N5724 is not listed in CGCG or RC3. NGC 5744 (14h 43.9m -18° 29') Stone's position is 14 45.2 -18 29 (2000) or 1.3 tmin E of E580-G14. N5744 is identified as E580-014 in the RC3, ESO (uncertain) and SGC. Not identified as N5744 in MCG. ESGC identifies N5744 as E580-023 = M-03-38-007 at 14 46 38 -18 30 48(2000) in which case Stone's position is 1.4 tmin W! The PGC errata list states that N5744 ‚ E580-014 and is instead E580-023. NGC 5761 (14h 49.1m -20° 23') Discovered by Leavenworth (I). His very rough position is 14 49.5 -20 18 (2000). RNGC, ESO-LV and RC3 identify N5761 = E580-G39, at GSC position 14 49 08.4 -20 22 34. In ESGC and a previous RNGC errata list, Harold Corwin identified N5761 as E580-G40 at 14 49 49.9 -20 16 41. Leavenworth's dec is a better match with E580-G40 (generally it is RA that is significantly off in the Leander-McCormack list). But, E580-G39 is brighter by ~1 mag. NGC 5785 (14h 53.5m +52° 05') Discovered by Swift (VI). His position for N5785 is 30s E and 4' N of N5783 so the equivalence with N5783 (as given in UGC and CGCG) is uncertain although Swift's description of "F* nr foll" appears to describe this gx. Strangely, the NGC entry for N5783 (attributed to Swift VI) does not appear in his list so must have been communicated directly to Dreyer. Listed in RNGC Corrections #7. NGC 5788 (14h 54.5m +52° 06') Discovered by Swift (VI) as the sf of a pair with N5785. Not found by Bigourdan and listed as a dubious NGC object by Hagen. Swift's position for N5788 is 14 54 27 +52 06.5 (2000) or 1.2 tmin E and 3' N of M+09-24-049 which is identified as N5788 in RNGC. As this gx is SW of N5785 the RNGC identification appears very unlikely. N5785 is listed as nonexistent in RNGC and = N5783 in UGC. M+09-24-049 is not identified as N5788 in CGCG (273-32) or MCG and is not catalogued in RC3. Written up in RNGC Corrections #7. NGC 5795 (14h 56.3m +49° 24') Discovered by Swift (VI). The discovery was communicated directly to Dreyer. There is no object at his position but 50' N is U09617. Harold Corwin argues this gx (identified as N5795 in RNGC and RC3) is correct based on Swift's description "vF, pS, eE, spindle, pB* close to p end; [N5794/5804/5805] in field", although the pB* is at the following end. This gx is not identified as N5795 in UGC, MCG or CGCG. Malcolm Thompson feels (R)N5795 = U09617 is very unlikely since it is 50' N of Swift's position and U09626 is more likely. Listed as a dubious object by Hagen. NGC 5840 (15h 04.3m +29° 30') Discovered by Swift (IV). Listed as nonexistent by Sulentic. There is an extremely faint gx on the DSS at approx coordinates of 15 04 12 +29 29 00 (2000). NGC 5865 (15h 09.8m +00° 32') Discovered by WH (II 684). Observed in the same sweep as II 545 = N5869. It is likely that II 684 refers to d'Arrest's N5868 although both objects were probably accidently given identical descriptions (pB) by H. See Dreyer's Scientific Papers of WH, 1912. If N5865 is a duplicate of N5868, then WH's number could apply by historical precedence. The data for N5865 in RNGC applies to N5869 and the U2000 labels N5869 as N5865. The UGC entry (U09742) for N5865 = N5869 should read N5869. NGC 5869 (15h 09.8m +00° 28') Pair w/N5868. RNGC equates N5868 with N5869 but the NGC positions indicate that N5868 = N5865. Data listed under N5865 in the RNGC. Since this gx is the brighter of the pair and JH only saw one object this must be h1908 = N5869. MCG and Engelhardt identify this gx as N5865. NGC 5881 (15h 06.3m +62° 59') Discovered by WH (II 818). In Scientific Papers of WH, Dreyer notes that the listed RA in GC and NGC was 2 tmin too large. Because of this error, Bigourdan and d'A could not locate N5881. Dreyer's correction places N5881 at roughly 15 07.2 +62d 56.5' (2000). Less than 1 tmin further W is IC 1100 (discovered by Swift) at GSC position 15 06 20.8 +62 58 52 (J2000) which is the only reasonably bright galaxy in the vicinity. The RNGC misidentifies N5881 = U09764 but this is clearly erroneous as U09764 is located at 15 09.8 +65d 05' (1950), over two degrees from the NGC position. N5881 is identified as IC 1100 in UGC, MCG, CGCG and RC3. Listed in RNGC Corrections #6. NGC 5892 (15h 13.8m -15° 28') Discovered by Stone (I). His rough position is 2.3 tmin E and 30' N of M-02-39-007, which is identified as N5892 in RNGC and RC3. Stone's description gives mag 16.0 and size 2.5' which implies a large galaxy, which does match this large, low surface brightness object. M-02-39-007 is not identified as N5892 in MCG and this gx is identified as A1511-15 in RC2. NGC 5919 (15h 21.6m +07° 44') Swift's position is 10s W of M+01-39-020 = Z049-142 at 15 21.5 +07 43 (2000). The listed dimensions of 3.0'x2.0' in MCG and 3.3'x2.2' in RC3 must refer to a combined size for several galaxies. There are at least 6 small nearby galaxies on the POSS so the ID is not certain but based on this visual observation it appears likely that N5919 = CGCG 049-142 (triplet?). It is possible that my observation of a 2nd or 3rd object includes CGCG 049-144 which is only 1' ENE. Harold Corwin came to the same probable conclusion regarding ID's. DSFG gives 11.4V which is much too bright (PGC has 12.4B). GSC position 15 21 36.9 +07 43 10. NGC 5942 15 31.6 +07 19 Discovered by Swift in a compact group. This gx is identified as N5941 in RNGC, CGCG, MCG, RC3, U2000 and DSFG! These catalogues identify N5942 as HCG 76d which is likely an anonymous gx (not found by Bigourdan). Based on my visual observation of the 4 members in the group I suggested to Harold Corwin that the ID of N5941 was in error which led to his reassignment of ID's bases on Bigourdan who only observed the 3 brightest gx's (HCG 76b,76c, 76a). Bigourdan stated that the orientations of N5941/5942 were nf/sp which places N5941 slightly east of N5942. GSC position 15 31 36.9 +07 18 44. |
