some double stars whose orbit can be tracked in a human lifetime?

[Robstargazer15]

Is there any other double stars whose orbits can be tracked in my life time?

I have split Porimma and 70 ophiuchi already for future observation to see if i can tell that the secondary moved.

Do you mean a complete orbit..or just a section to determine the orbit?

Couteau in his "Observing Visual Double Stars" has a comprehensive list and obsrvering details.

I guess most stars orbits are partially seen in a human lifespan.

In Couteau's book, table 6.11 there are almost 30 visual stars listed with a period of 60 years or less.....

I have Couteau"s book I'll have a look for you, one that I like to follow is Zeta cancri, the A-C pair are a good reference for the movement of the AB pair.

One to keep an eye on is epsilon Aries as it is believed to have passed the maximum separation and iis closing, The orbital period is between 300-600 years. If it is nearer 300 then it will start showing some significant change within our lifetimes.
