It seems the position angle and separation of doubles is somewhat sketchy, it seems it is something amateurs don't regularly log. I think this is something that amateurs can contribute to the science. I have gotten into the habit of orienting N/S and E/W in the eyepeice by moving RA and Dec until it becomes clear.
I googled Gamma Virginis and the first hit was a wiki page
http://en.wikipedia.org/wiki/Gamma_Virginis
It says .9 arc seconds for 2010. But that's based on an orbit calculated in 1937.

Anybody know what the separation for Gamma Virginis will be in 2010? I had some fun splitting double stars the other night and would like to see this one again.
I barely split Zeta Aqr which is about 2 arc seconds wide. The seeing was pretty good early in the evening but degraded later so I packed up and was home by 10 pm.
