A wide triple star, between the head of Aries and the base of Triangulum; being the centre of the group mentioned as headed by 10 Arietis, above described. A 5½, white; B 10½, blue; and C 9, lilac. A is the apex of a scalene triangle, with B in the nf and C in the np quadrant, in a field otherwise barren; but immediately followed on the parallel of A, by 16 Arietis. A and C of these three stars are registered as H VI 69, thus:Pos. 281°15' Dist. 89".47 Ep. 1781.99Sir James South next measured it, and foundPos. 277°58' Dist. 105".258 Ep. 1823.97which great discrepancy, John Herschel is inclined to attribute to the construction of his father's micrometer at that early period; the effect of which is to throw great uncertainty on the earlier distances of all the wide stars: "fortunately," adds he, "these are the least replete with interest." This object was evidently not scrutinized with rigour, since B was overlooked by former observers. Piazzi, in referring to C, says, "In eodem paral. 8" temp, circiter, præcedit alia 9* mag."
