Observing Notes

Captain William Henry Smyth
Oct 30, 1833    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A close double star, on the sf extreme of the Fishes' kheït, or ribbon; and it lies on a line shot from ζ Piscium to α Arietis, at about a third of the distance. A 7, silvery white; and B 7½, white. Piazzi notes No. 209 as being H 84 V., but he evidently alludes to the distant companion in the np quadrant. This very fine object, resembling η Coronæ, is Σ's No. 186, and registered "vicinæ" in the Catalogue of 1827; it has since been thus measured at Dorpat:
    Pos. 64°72'  Dist. l".232  Ep. 1831.12
[ 74° 0".70 2019 WDS]
[HD 11803 has a known orbit of 165 years and a fairly high eccentricity of 0.72, it has thus completed over one orbit since discovery]
