No other measures. The proper motion of the principal star 
is given from meridian positions:

I do not find any proper motion assigned to this star. 
1 Aquilae (4.5...13.2) 
R. A. 19" 30 m 31 s Decl. — i°33' 
A is reddish and variable, 7 m to 13 m. At the time of these 
measures the magnitude was about 10.7. These stars are 
respectively DM (49 0 ) 3064 and 3065, and closely sf 6 Cygni. 
The micrometer positions are not accordant in distance, but 
probably without change.
