In Magnitude, nearly constant. 



In Colour, brilliant and pronounced ; A, nearly always rich yellow ; B, rather 

 variable, from blue to greenish, and probably light violet. 



In Position and Distance, constancy nearly prevails, large errors of observation 

 being allowed for. The B. A. C. proper motion of A, if unpartaken of by B, would 

 have decreased the position by 22°, and increased the distance by l"-3 in 30 years; 

 we may therefore say with confidence that in character the pair is a slow binary.
