In the General Catalogue this is called SD(4°) 3246; 
should be (3 0 ) 3246. No change since 1868.

Rejecting the single measure of 1878, the other positions give 
for the proper motion of A :

The proper motion of the principal star is extremely un¬

Further measures should be made for a final correction to 
the proper motion. In this interest, I have added a third 11 m 
star.

These measures should be repeated at a later date for the true 
proper motion of A, as the first position by Dembowski depends 
upon a single night. The three measures (1864-1909) give: 
o"i47 in I47°4 
The relative motion of A with respect to B from the meas¬ 
ures (1876-1911) is: 
o"o49 in 244? x
