Observing Notes

Captain William Henry Smyth
Sep 13, 1839    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A close double star, between the head of Pollux and the preceding claw of Cancer; following the former nearly on the parallel, at about 5°½ distance. A 7, pale yellow; B 12, lilac. This delicate object is not 11 ♅. I., as supposed by H. and S., who mistook for it a very neat double star about 3' preceding [HR 3164], and a little north of the parallel. On the arrival of the Dorpat Catalogue, it was found that Σ. had observed both; 11 ♅. I. being Σ.'s 1177; and the one before us, his No. 1186, thus measured:
    Pos. 218° 52'  Dist. 3".18  Ep. 1828.26
[WDS 212° 3".30 2018 ]
This occasioned some confusion, as I had formerly measured 88 H. and S. with some degree of exactness at the equatoreal, and also, they being of the 7th and 8th magnitudes, with much facility; but on fixing the mean apparent place at the transit-circle, discovered the error. My measures of 1832 were:
    Position 354°.2 (ω 8) Distance 3".8 (ω 6) Epoch 1832.76
