Burnham: Measures of Proper Motion Stars 
For the proper motion of the close pair. The relative motion 
in the large stars is in the position-angle. For the movement 
of A we have:

The last measures connect the principal star of H 1606 with 
the principal star in h 2099. The greatest length of the nebula 
is about 89" in the direction of 25 0 .

There is a decided motion in angle and distance from the 
proper motion of A. This from the measures (1873-1909) is: 
o"o 62 in 233?9 
For verification a third star is connected.

As A and B appear to have a common proper motion, I have 
connected a faint star for an independent value of this move- 
ment. From meridian positions this is:

As the components 
do not differ greatly in magnitude, the 
proper motion may be 
in either. The apparent motion of A is: 
0*031 in 329?o 
To determine this, I have connected a 
third small star.
