Change from proper motion of A. The measures of AB 
(1875-1910) give: 
Measures o"o76 in 83?2 
Greenwich 0.066 in 79.6 
With the measures by Engelhardt in 1894, we have for the 
proper motion of AB : 
o"325 in 79° 7 
The proper motion of the bright star is given in the cata¬ 
logues :

As this appears to be a pair of the 61 Cygni type, I have 
connected a very faint star.

0.288 in 270.0 
For the proper motion of AB. There is a 14 m star near A:
