The companion, B, at 289, 117," is magn. 6.30, as derived from 38 observations with double image photometer. Its magnitude is 8.0. in the Bonn Durchmusterung. Accordingly, it was not observed with the meridian photometer, nor at Potsdam. 1171. S. M. P. 750. 1180. Pleione. Spectrum 8, having also Bss and other lines bright, in 1888 and 1896.
