Subject: NGC 4501 - NGC 5000 revised notes 3/17/05 From: Steve Gottlieb Date: Mon, 21 Mar 2005 23:59:32 -0800 To: Bob Erdmann [This file updated by seperate e-mail dated 02/19/2006] NGC 4501 = M88 = U07675 = MCG +03-32-059 = CGCG 099-076 = PGC 41517 12 31 59.0 +14 25 10 V = 9.6; Size 6.9x3.7; SB = 13.0; PA = 140d 17.5": very bright, very large, elongated 5:2 NW-SE, brighter core, intense very small or stellar nucleus. A faint double star is embedded at the SE end (mag 13.5/14.5 at 20"). A brighter double star mag 11/12 at 30" is 5' S of center. Located at the NE end of "Markarian's chain" in the core of Virgo cluster. ************************************************************ NGC 4502 = UGC 07677 = MCG +03-32-060 = CGCG 099-076 = LGG 289-083 = PGC 41531 12 32 03.3 +16 41 16 V = 13.9; Size 1.1x0.6; SB = 13.2; PA = 40d 18" (4/5/03): very faint, small, elongated 3:2 SW-NE, 0.6'x0.4', low surface brightness.

WH's description is of a (resolvable) cluster (III 18). Described by JH (h1315) as "eF, the following of 2 in fld." [with N4496]. But this object was not recovered by Bigourdan and there is nothing at WH's position. JH's brief description probably applies to a faint star. Reinmuth also lists this object in Die Herschel-Nebel although he questions if it is a mag 14 star (it is). Corwin feels WH may have made a duplicate observation of N4496 (using a different reference stars) which was observed on the same night. N4505 is also equated with N4496 by Carlson. See NGCBUGS. ************************************************************ NGC 4506 = UGC 07682 = MCG +02-32-120 = CGCG 070-152 = PGC 41546 12 32 10.5 +13 25 10 V = 12.7; Size 1.6x1.1; SB = 13.2; PA = 110d 17.5": faint, small, slightly elongated E-W, diffuse, very weakly concentrated core.

Located 5.2' SW of mag 5.8 SAO 203621 which detracts from viewing. This is a Seyfert galaxy and possible member of the Centaurus galaxy cluster (Abell 3526). ************************************************************ NGC 4509 = UGC 07704 = MCG +05-30-018 = CGCG 159-015 = Mrk 773 = PGC 41660 12 33 06.8 +32 05 32 V = 13.5; Size 0.9x0.6; SB = 12.7; PA = 155d 17.5": faint, small, slightly elongated SW-NE, almost even surface brightness. Located 4.5' NW of a bright double star ?1653 = 8.7/9.2 at 8". ************************************************************ NGC 4510 = UGC 07679 = MCG +11-15-058 = CGCG 315-041 = PGC 41489 12 31 47.2 +64 14 01 V = 13.0; Size 1.5x0.9; SB = 13.3; PA = 153d 17.5": faint, very small, very small bright core, stellar nucleus, very small halo.

A mag 14 star is close south, in the direction of elongation. UGC 7691 lies 11' N. ************************************************************ NGC 4512 = N4521? = U07706 = MCG +11-15-061 = CGCG 315-046 = PGC 41621 12 32 47.6 +63 56 21 See observing notes for N4521. Identification uncertain. JH's position for h1321 = N4512 precesses to 12 32 08 +63 44 (2000). This position is 10' NNE of U07700 = M+11-15-060, the galaxy identified in all modern catalogues as N4512. His single description of "pB" certainly does not apply to this low surface brightness galaxy and it is strange that he would not mention much brighter N4521 just 4' NE observed in the previous sweep (described as a "nova" with a 20' error in declination!). Bigourdan was not able to recover N4512 and Reinmuth states "no pB neb found, =N4521?". His description for N4521 mentions U07700 as a "F neb ssp 4.0" although it is not identified as N4521. Corwin suggests that N4512 may also be identical to N4510 as this would require a 30' error in dec only, although this galaxy is certainly fainter than N4521. So, the identification with N4521 is tentative.

Third of four in the field and located 11' SSE of N4602. Discovered by Peters at 12 40 45 -05 08.8 (2000). The discovery must have been communicated directly to Dreyer as it does not appear in either of his Copernicus lists. This object is listed as nonexistent in RNGC based on Carlson's paper on NGC corrections which states it was not found at Helwan observatory. RC3 identifies N4605 = M-01-32-037 at GSC position 12 40 45.2 -05 18 11 (2000) which is exactly 10' S of Peter's position. Although, there is no visual description in the NGC, this identification (which is given in ESGC) is reasonable assuming a single digit error in declination by Peters.

Uncertain identification. Discovered by JH (h1390). Described as "B, E. RA ill observed." His position is 12 42 15.7 +03 03 32 (2000) although the declination is not stated as uncertain as in the description. Reinmuth notes "not found; N4624 = N4636? (repeated by Carlson). Corwin notes in NGCBUGS "During the same sweep, he [JH] made a one-degree error in the polar distance for NGC 4636, an error that he himself suggested, and that Dreyer finally rectified for the NGC. Thus, NGC 4624 cannot be NGC 4636 as suggested by Reinmuth and adopted by RNGC." My visual observation described N4636 as only slightly elongated but it is certainly very bright. Another possibility is N4624 = N4600 which is moderately bright and closer to h's declination. Instead, Corwin suggests "it is most likely NGC 4665 which JH described as ``B, pL'' in two other sweeps. This, and the appearance of the bright bar of the galaxy, matches his terse description for N4624, ``B, E.'' In addition, his declination is correct for all three observations. There is a faint possibility that N4624 is N4600, but JH's two observations of that make it ``F, S'' in contrast to his note on N4624. In addition, the declination of N4600 is off JH's measured dec for N4624." ************************************************************ NGC 4625 = UGC 07861 = MCG +07-26-038 = CGCG 216-018 = IC 3675 = PGC 42607 12 41 52.7 +41 16 26 V = 12.3; Size 2.2x1.9; SB = 13.8 13.1": fairly faint, fairly small, round, brighter core.
