92. This system has a very rapid motion in distance and angle of position. Struve's formulæ, derived from his observations, are,

Distance at epoch t = 11′′-252+0"·206 (t− 1832·63);
Angle of position at epoch t = 351°72-0°823 (t− 1832·63).
The distance therefore changes uniformly, but the angle does not so.
