Burnham: Measures of Proper Motion Stars 
The distant star is DM (26°) 470. From the measures of the 
small stars (1852-1912), we have for the proper motion of 41 
Arietis: 
AB R. A. + o"o85 Decl. — 0H13 
AC 0.073 0.105 
AD 0.043 o.m 
+ 0.067 —O.IIO 
Therefore the corrected proper motion is: 
o"i2Q in 148:6

As there has been no change in the small star in 80 years, it 
is safe to say that the Struve pair has no proper motion. There 
probably is an error in the R. A. sign in one of the Greenwich 
catalogues:
