 Annual proper motion in R. A., + ".125 ±".012. 

 Relative parallax, + ".021 ±".010. 



No other determination of this parallax has been published. Boss gives +0".140 for the 

 proper motion. 



There is a companion two magnitudes fainter with which this star forms 2 208. The 

 two are now very close. The orbital period must be long.
