comparison. 1 
One of the nearly equal 
components has a small proper motion. 
The four positions by 
(3 and Doo on 13 n (1879-1912) give for this movement:

The place given in Part I of the General Catalogue is that 
of 31 Comae, which is 2 m 25 s following, same declination. The 
R. A. should be as given here. 
From the four (3 measures of the small star (1878-1912) the 
proper motion of 30 Comae is: 
0)067 in 295)8 
This has been given from meridian positions:

The proper motions in A. G. Berlin are: 
A o'.'o6o in 289)5 
B 0.042 in 270.0 
As there has been no change in these stars in more than 80 
years, it is evident the motions are exactly the same.

The proper motion of AB, if any, is very small. 
As there has been no material change in these stars since 
1836, whatever proper motion there is, is common to both.
