If the larger star has any proper motion, it is wholly un- 
certain from meridian positions:

The faint star makes a nearly equilateral triangle with A 
and B. The proper motion of 28 Aquilae is not certain:

To determine which of these large stars has the proper 
motion, I have measured two faint stars. 
From the measures of AB (1875-1910) this motion is:
