Captain William Henry Smyth
Oct 12, 1833    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A very neat double star, between the tips of the Bull's horns; and mid-way between the Pleiades and δ Geminorum. A 7, white; B 7½, pale blue. This elegant object is 75 ♅. II., and was noticed thus by Piazzi: "Duplex; minor ad austrum; medium observatum,"—which method perhaps prompted him to assign the slight proper motion he has registered to A, hut which has not been confirmed. A consideration of all the measures of this star, and allowing for probable small errors of observation, identifies its fixity. These are the data:

    ♅.        Pos. 192°45'  Dist. 5".03  Ep. 1782.94
    H. and S.      194°01'        5".66      1821.97
    Σ.             196°46'        4".89      1829.63
    D.             196°20'        5".15      1832.87
   [WDS            209°           4".60      2020   ]

A proper motion is ascribed to A, in which it is probable that both stars partake. The best valuations give:

    P....  RA +0".11  Dec. -0".06
    B...      +0".08       -0".07
   [Hipparcos +0".01148    -0".03720]
