Triple of two brighter and one faint star. Project data for the AB pair seems to be from 1830, newer data is more consistent with my measure, but the AC pair had only two measures listed in the WDS, 1910 and 1923, and my
measure seem to fall between these two, quite mystifying. Measurements, AB 28.13 sec at 016.3 deg PA, AC 51.37 sec at 325.0 deg PA.
