Union Observatory
Innes' star was discovered in 1920 by Robert T. A. Innes in Union Observatory, Union of South Africa, who had discerned its large proper motion and a parallax of 0.337 arcsec. The discovery was published in "Circular of the Union Observatory" No. 49, hence its discovery name is "UO 49", or "In UOC 49". However, "UO" designations should be used with caution since they are often not unique for each star: the number in the name is the number of "Circular", so all stars published in one "Circular" have identical names. So, all other newfound stars, published in the 49th "Circular", may be named "UO 49" too.
