One of these stars has a considerable proper motion. From 
the four positions by A, Fr and | 3 , the apparent motion of 
B is:

To determine which is the moving star, I have measured a 
third star.

Nothing can be known of the orbit of this binary before the 
end of this century, and probably not then. 
For the proper motion of
