From the measures of these faint stars (1903-1911) we have 
for the motion of A : 
AC R. A. + 0IT41 Decl. + 0^046 
AD 0.159 0.066 
+ 0.150 +0.056 
Therefore the proper motion of the principal star is: 
o"i6o in 69? 5 
The values heretofore given are too large:

No sensible change in AB in the last half-century. No other 
measures of C. 
The proper motion of A is too small to be certain from 
meridian positions.

The ten positions of this 
very faint star (1877-1911) should 
give the proper motion of the binary system with substantial 
exactness:

» in 95?2 
The correction to the former values i 
is small.
