Combined magnitude for the AB system is V= 2.50.
You can use my chart at:
http://ar.geocities.com/varsao/Carta_del_Sco.htm

However this star is too faint for the current state. We'll use it when the
star is back (if it is...) to minimum at V= 2.32.

The combination of magnitudes of close doubles for naked eye observation has
been one of my priorities in recent years and it ended up with the discovery
of delta Velorum eclipses: was the pair AB 1.95 or 1.89? The night I was out
there to do some checking, the star was at 2.25... !!!!

Regards,
Sebastian.
