The proper motion derived from the meridian positions is 
very uncertain:

Assuming the fixity of the smaller component, the proper 
motion of Groombridge 3357 is :

It would be generally unsafe to assume that a star of the 
magnitude of B was fixed, but in this instance from all the 
data it appears to have no sensible movement. To make this 
certain hereafter, I have measured a third small star from 
both A and B.

The larger star, B, is a very close pair (= P 1138). In my 
General Catalogue the proper motion of L 40848 is erroneously 
given to P 1138. The meridian positions give the latter no 
sensible motion. The only direct measures of these stars are 
the following: 
1894.04 133-15 i 67"76 2n Eng 
1908.34 134-91 165.61 3 n p
