    Hello to all,


    Kochab and Zubenubi had equal RA's in 1995 sometime between Sep 15th, and Oct 01st.

    On Sep 15th, Kochab RA was greater than Zubenubi's, and

    on Oct 01st, Zubenubi RA was greater than Kochab's.

    Source : Simbad Catalog

    In between, it remains possible that there were more than just one date and time when both RA's were exactly equal, because of Nutation.

    Best Regards to all

    Kermit
