Stars in the field of Bochum 15 appear in SIMBAD with a mix of precise, accurate, and missing coordinates. Several HD and DM names are missing. Below I show positions for all the stars along with usual IDs and also proper motions. The motions are in units of milliarcsec/year, and have typical errors of 1-2 mas/y. Most of the stars show only reflex motion toward the solar antapex, with stars such as 7 (almost certainly a foreground dwarf near G0) conspicuous by their contrary motion. Since the stars are spread over an 8 square degree region, it would seem speculative to suggest they form a cluster only on photometric grounds (well, the first paper calls it a "young stellar aggregate"). The position for the center of the group is about 45' in error in WEBDA and SIMBAD. The one shown below is simply for the middle point of the stars shown on the finder chart. =============================================================================== Coordinates and identifications for stars in Bochum 15 version: 23 Jan 2008: coords/IDs for star 8 corrected 4 Dec 2003: V mags added 13 Aug 2002 sources: 1977A&A....60..417J 1976A&A....46..287F field center: 7 36 34 -33 27.9 (J2000), midpoint of charted stars position/motion sources (column 's'): T Tycho-2 (2000A&A...357..367H, I/259) U UCAC1 (2000AJ....120.2131Z, I/268) Name RA (J2000) Dec s GSC Tycho-2 V remarks 1* 7 41 18.09 -32 30 36.3 U 7110-1632 7110-1632-1 10.3 CD-32 4290 2 7 41 40.69 -32 37 41.5 U 7110-3233 7110-3233-1 10.2 CD-32 4296 3 7 41 13.32 -32 38 38.2 T 7110-3221 7110-3221-1 7.7 HD 62150 4 7 39 49.34 -32 34 42.2 T 7110-0168 7110- 168-1 7.7 HD 61827 5 7 39 21.02 -32 31 05.0 U 7110-1824 7110-1824-1 9.8 CD-32 4257 6 7 39 12.27 -32 33 35.4 U 7110-0560 7110- 560-1 11.8 7 7 37 59.29 -32 41 40.8 U 7109-0666 13.0 8 7 34 16.24 -34 04 02.2 U 7113-1752 12.4 9 7 34 56.22 -32 33 11.1 U 7109-0054 7109- 54-1 11.8 10 7 33 00.27 -32 33 11.0 U 7109-0828 7109- 828-1 10.7 CD-32 4140 11 7 35 11.65 -32 52 44.2 U 7109-1166 7109-1166-1 11.9 CPD-32 1587 12 7 34 11.81 -33 07 09.9 U 7109-1991 14.8 13 7 33 10.15 -33 27 41.2 U 7109-0731 7109- 731-1 10.8 CPD-33 1564 14 7 30 13.35 -33 24 58.2 U 7109-2747 7109-2747-1 9.7 HD 59776 15 7 32 23.42 -33 40 09.6 U 7109-0669 7109- 669-1 12.5 16 7 33 04.17 -33 46 07.2 U 7113-3140 7113-3140-1 12.1 17 7 35 42.29 -33 36 59.6 U 7109-0213 7109- 213-1 12.1 CD-33 3950 18 7 36 45.35 -33 45 17.7 U 7113-2402 12.1 19* 7 37 06.95 -33 16 10.8 U 7109-2357 7109-2357-1 11.0 CD-32 4215 20 7 41 47.91 -33 38 41.7 U 7110-0451 11.6 21 7 38 33.49 -33 23 38.7 U 7109-2549 13.4 22 7 38 45.01 -33 24 30.3 U 7109-1351 7109-1351-1 12.2 23 7 38 46.75 -33 24 27.2 U 7109-1293 7109-1293-1 12.4 24 7 39 30.68 -33 21 16.6 U 7110-1563 7110-1563-1 12.1 25 7 39 28.05 -33 33 56.7 U 7110-1737 7110-1737-1 11.9 26 7 39 21.86 -33 38 19.9 U 7110-1519 13.1 27 7 40 07.07 -33 32 32.4 U 7110-1171 7110-1171-1 12.2 28 7 40 09.54 -33 34 14.3 U 7110-2623 7110-2623-1 12.2 29 7 40 30.29 -33 30 44.6 U 7110-1517 7110-1517-1 10.1 CD-33 4026 30 7 41 39.98 -33 49 54.0 U 7114-1000 7114-1000-1 9.8 CD-33 4043 31 7 41 32.63 -33 51 00.1 U 7114-1450 7114-1450-1 12.3 32 7 39 52.33 -33 48 01.3 U 7114-1502 7114-1502-1 12.3 33 7 40 31.37 -34 01 23.0 U 7114-1032 11.9 34* 7 38 06.58 -34 12 33.9 U 7113-0938 7113- 938-1 10.9 CD-33 3986 35 7 36 42.04 -34 25 16.8 U 7113-2020 7113-2020-1 10.2 CD-34 3746 36 7 42 19.28 -34 46 04.4 U 7114-1275 7114-1275-1 10.5 CD-34 3821 37 7 41 43.43 -34 47 27.6 U 7114-2563 7114-2563-1 10.4 CD-34 3814 38* 7 42 54.87 -34 19 07.9 U 7114-0104 7114- 104-1 11.0 CD-34 3831 Notes 1 CPD-32 1683. 19 CPD-32 1621. 34 CPD-33 1629. 38 CPD-34 1586, _not_ 1589.
