From the large number of nights in the first position by 02 , 
the resulting proper motion should have a high degree of ac- 
curacy. As would be expected in a star moving at 
this rate, 
the correction is small:

It is not probable that the

star, 
9.5 m in DM, has any 
sensible motion. To determine this hereafter, I have measured 
a third star:
