Day shift yesterday (Nov 17) almost no beam due separator issues. 
Swing shift beam delivery started at 18-00, quality was bad, lots of FSD trips, current less then required 70uA. 
MCC took beam away again around 20-30 for 45 minutes to steer A2 apperture, as result stable 70uA beam operation overnight and morning.
