Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 4' and the class as 1 3 mN. He notes: "Observed by Gould (Cordoba Photogr. Plate 20) and shown in Harvard Annals 26, plate 8, fig. 2. On a plate taken with the 37-inch reflector of the Chile Station by H D Curtis this appears as a typical open cluster of bright and faint stars, medium rich, with strong central condensation, slightly unsymmetrical."
