The proper motions of the large stars (Groombridge 1996 1 
and 1997) are given from meridian positions: 
A o"n7 in 295?9 Schroeter 
0.071 in 317.5 Groombridge 
The proper motion is small: 
Boss o"o73 in 273? 1 
The measures of the small star will give an independent value 
later on.

No measure of this since 
1824. If the 
measure at that time 
was substantially correct, A and BC have a common 
proper 
motion. 
B and C make 2 1752. From meridian observations:

As there is no relative change in these stars, the proper 
motions, if any, would be exactly the same. To determine this 
movement later, I have connected a faint star.
