+8.22 = + .0028 ir=+ .00038. 



Probable error for unit weight, ± .0016 mm. = ±".024. 

 Annual proper motion in R. A., + ".050 ±".007. 

 Relative parallax, + ".006±".009. 



Other determinations of this parallax are: Mount Wilson (spectroscopic), +0".018; 

 McCormick, +0".005±0".007. Boss gives +0".024 for the proper motion. 



This star is 5' from 35 Leonis; the proper motions of the two stars indicate that there is 

 no physical connection between them.
