[AZ-Observing] Re: Rapid motion binary stars

Howdy all;

OK, here are the updated values for the NOTES column in the update of the
SAC double star database.

Brian Skiff, how would I put the new orbit data for Gamma Vir into Brian
Workman's spreadsheet?  I am not certain exactly what values go into which
cells.  If you would be willing to use the new info you have and get me an
uptodate and 5 years hence info, I would appreciate it.

If someone knows of another star that ought to be added to this list of
rapid motion binaries, let me know, please.

Thanks, as always;
Steve Coe
