Description:
At ~ ¼ ° SE of 70 Tau, located almost halfway between 63 Tau and 70 Tau, members of the Hyades.  This double star was not on my list and I discovered it by chance while carrying out the star counting in the Hyades.  The components are roughly of the same brightness.  Their weak luminosity prevents me from determining their color.  I used the Smithsonian Astrophysical Observatory catalog designations because, with my very great surprise, this double star does not appeared in the main double star catalogues, which would be a case of extremely rare exception.  In order to identify this double star correctly, I make several research in literature (Burnham's, Webb Society Handbooks), astronomy software (I use mainly The Sky) and on the Web.  I made several query on SIMBAD, and still here, this double does not seem to be noticed. I made a last research on an excellent reference which I have used for a few years for double stars, the Washington Double Star catalog (WDS), and nothing at the co-ordinates of this double star. B. Skiff confirms me that this double star is too large in separation, for a 8 - 8.5 double star, to appear in old catalogs and it remain a binocular object
