Captain William Henry Smyth
Aug 26, 1835    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A bright star with a distant companion, on the left thigh of Hercules, and nearly in a line with the last two objects. A 3, pale yellow; B, only inferred; C 10, dusky. The proper motion in space of the principal is thus valued :

    P....  RA -0".24  Dec. -0".09
    B....     +0".08       -0".07
    A....     +0".07       -0".07
   [Hipparcos +0".03541    -0".08530]

Here A forms No. 2093 of the Dorpat Catalogue, and was described in 1827 as a first-class "vicinissimae," like ζ Herculis and ν Coronae; and its components were registered of the 4th and 8th magnitudes. Many were the efforts I made at distinguishing a proximate comes, but without effect; and when Σ.'s measures arrived in 1837, finding it was styled "simplex," I relinquished the attack. Having, however, heard of its subsequent elongation, I re-examined it at Hartwell, and think I may safely give the above details, as tolerable estimations of an egg-shaped object.

This star is sufficiently conspicuous to the north-east of Gemma, at about 16° distance; and it is also 19° from Wega, on its western parallel; it forms an equilateral triangle with its own ζ and π.
