150mm f/17.6 refractor by Tully 1827
A neat double star, on the animal's chest; and 16 east-north-east of Capella. A and B, both 7½, and silvery white. This object is No. 61 of ♅.'s List of 145, but no measures were given; and Piazzi noted it double, in these words, " Duplex. Comes ejusdem magnit. 2" circiter temporis sequitur, 15" circiter ad boream," thus assuming the opposite quadrant to that which has been adopted. The other measures are:H. and S. Pos. 252° 39' Dist. 15".96 Ep. 1823.33From a comparison of these results the relative fixity of these stars may be deduced; but B has a slight proper motion in declination, amounting perhaps to -0".07 per annum, which is a mean of several authorities. [Gaia DR2 data shows both stars sharing very similar proper motion and parallax, with B moving at -24.026 mas in RA and -41.119 mas in dec]
