We are running production at 30 micro-A, smoothly. 

Escorted access twice Yesterday: Bogdan tried to fix the Left VDC U plain inefficiency issue. Still not stable but no large impact is expected. No plan to touch it before Tuesday. 

Back to production at ~19:30. During the first run (4547), LHRS S2 HV accidentally off for the first half of the run.  Beam lost  due to vacuum problem in the west arc and returned soon. 

Owl shift crew noticed the camera for visual hall inspection was not working, at ~1:00. Fixed by Florian. 

>From MCC, the plan is to continue production beam delivering until beam test on Monday. We will keep taking production run with Tungsten 2.8%.
