Burnham: Measures of Proper Motion Stars 
B is DM (24°) 3168. The proper motion of 70 Herculis is 
small, and somewhat uncertain :

Boss 0.018 in 266.8 
As B appears to share the motion of A, whatever it is, I have 
connected with it a faint star.

There appears to be a slow decrease in the angle, the distance 
remaining constant. The proper motion of 54 Ophiuchi is un¬ 
certain in amount and direction.
