150mm f/17.6 refractor by Tully 1827

A most delicate double star, on the np limb of Deltōton; and a line projected from γ Andromedee to pass between α and λ Arietis, will pass over it in about mid-distance. A 5½, bright yellow; B 15, dusky. This object was marked "difficilis" in the Dorpat Catalogue of 1827. It lies diagonally between two small stars, one of which, 10th magnitude, precedes it by 9s.0; and the other, a deep orange-coloured 8th magnitude, follows by 14s , with a little neighbour 2s farther off. Proper motions in space, but under conflicting values, have been assigned to ε; thus:

P.... RA -0".08 Dec. -0".10
