discov_num notes refcode
CHR 224 AC. Surprisingly, no record of this wide companion to the 0".8 pair
I 152 is listed in the WDS, despite 17 observations spanning 90+ years
since Innes' discovery in 1896. Misidentification appears ruled out, I__1897b
since both the Innes pair and the new component are seen on two
separate occasions. Hrt1996b
