Observing Notes

Captain William Henry Smyth
Jan 11, 1835    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A double star, in the cluster on the Bull's shoulder. A 8, bright white; B 14, fine blue. This most delicate object was discovered by Σ., and entered as No. 444 of the great Dorpat Catalogue, with these measures:
    Pos. 338°.97  Dist. 3".277  Ep. 1832.34
[WDS 338° 3".40 2018 ]
As the same astronomer got an angle of 334°.4 in 1831, it may be well for those who have means equal to the task, to watch this pair closely. But any discrepancies at present must be referred to the extreme difficulty of the stars.
