BD+68°946 alternate catalog names (with sources)
* AOe 17415-6: Seen in pre-1970 papers (e.g., (Hertzsprung, 1915: "Effective wavelengths of absolutely faint stars", Table I; van de Kamp, 1969: "Stars nearer..."). Discussion on the CosmoQuest forum revealed this was from Oeltzen's Catalogue of Argelander's Southern Zones, compiled 1857-1858 by astronomer Wilhelm Albrecht Oeltzen. Number might be truncated in narrow tables (Crissman, 1952).
* Askloef or Asklöf 1851: Appears to be from a star catalog started by astronomer Sten Asklöf in the 1920s, based on work at McCormick Observatory and at Stockholm Observatory in Sweden. The catalog was continued by others (Osvalds, 1957: "Trigonometric parallaxes..."). Do not confuse with McCormick/ Vyssotsky catalog.
* CHARA 62 Aa: Designation named for the Center for High Angular Resolution Astronomy (CHARA) at Georgia State University, in a program to detect binary stars by speckle interferometry (McAlister, Hartkopf, Hutter, et al., 1987: "ICCD speckle observations..."). A detection was made for BD+68°946, and it was added to the CHARA catalog. However, Blazit, Bonneau & Foy (1987: "Speckle interferometric measurements of binary stars: IV.") failed to replicate earlier findings for BD+68°946, and the CHARA designation was dropped from use for this star. "Aa" indicated primary and secondary stars.
* Eggen 342: Eggen's 1968 catalog of M-dwarf photometry, from "Narrow- and Broad-Band Photometry of Red Stars. II. Dwarfs" (Wilson & Woolley, 1970: "Calcium Emission..."). Do not confuse with Eggen's 1979 catalog of bright, high proper motion stars.
* PM 17367+6823: Designation from Eggen's 1979 proper-motion catalog ("Luminosity and motion..."). Not the same number given in the "Identifiers" section on SIMBAD's webpage for BD+68 946 / GJ 687; "PM" in SIMBAD might refer to a different catalog.
* Vyssotsky (Vys or Vyss) 322: A common variant name for the McCormick (MCC or McC) I.D., using the astronomer's name instead of the observatory (Wilson, 1967: "Radial velocities..."; Weis, 1993: "Photometry of...").
* W 10198: Variant way of writing GCRV 10198 in SIMBAD (Abt, 1973: "Catalog of...").
* Yale 4029: Yale parallax catalog (Eggen, 1955).
Stellar designations based on the Cincinnati catalogs of 1918 and 1920 had no common editorial standard and will be encountered in a variety of formats in 20th-century papers (for this star, 18C2354, Ci 18:2354, Ci (18) 2354, Cin 18,2354, Cin 2354, etc.). It is also unclear which catalog is being used if the "18" or "20" is dropped, though "CC" is sometimes used for the 1920 catalog (CC 1053 for this star). This seems trivial but becomes relevant if word or phrase computer searches are employed.
Giclas catalog numbers might have an extra "0" in them for this star, which in SIMBAD is G 240-63: e.g., G240063 (Greenstein, 1989: "Bolometric luminosities..."), G240-063 (Oppenheimer, Golimowski, Kulkarni, et al., 2001: "A coronagraphic survey..."). Again, a computer search issue.
