[From entry CLXXX 61 ♅ VIII, NGC 1778...] Just to the north of the parallel, it is followed by the beautiful double star Σ. 644, which, from its aspect, being more likely to prove an optical object than the rest, was carefully measured, as above. The determinations of other astrometers are:

    Σ.  Pos. 219°12'  Dist. 1".61  Ep. 1828.60
    H.       224°19'        l".99      1830.05
   [WDS      221°           1".60      2019   ]
