WDS HJ 2067 – Double star in Cetus
The Washington Double Star Catalog lists the separation between these two stars as 31.0 arc seconds, and the position angle as 91 degrees. I measure the position of the left 13th magnitude star as [01 39 23.30, -17 47 37.8] and of the right 7.6 magnitude star as [01 39 21.21, -17 47 35.5]. This gives a separation of 29.9 arc seconds and a position angle of 94.4 degrees.
