We made good progress identifying the issues, in particular isolating the noise affecting our measurement. We would like to spend more time during next MD to eliminate/minimize the noise.

I would point to temperature fluctuations as the culprit.
The MO/LO system appears to be healthy.
Nothing was changed in the MO/LO distribution system between the MCC and NL in recent years.
The rack temperatures nearest the amp that inputs into the drive line is fluctuating at least twice as much as it did last year.

Body: 

Disconnect switch was exercised and power was restored to power supply. Associated EPAS paperwork has been prepared in the event that the supply trips again to troubleshoot. Supply was turned on and restored to Setpoint and handed over to OPS. Not sure if the trip is related to the NMR oscillations on logentry 4364206. DCP will monitor the supply.

Body: 

Before Apr 23 the charge asymmetry was averaging ~ 58 ppm. Apr 23 was accelerator maintenance day and the beam came back at the midnight.

After the beam came back the asymmetry was averaging ~ 200 ppm. We run the feedback during the run 17398 and brought the asymmetry back to ~0.

PITA voltage is set to - 2914. Earlier it was -3047.

FFB Restoration:

Cavity tripped, needed to re-LEM, etc...

Allsave after above.

Steering through Hall A line looks good after some slight touches (Figure 1).

Opted not to balance box supplies, as this would take nearly all alloted time, and it's already close (Figure 2 shows the difference). Given upcoming pass change, will leave this to happen at that time.

Seemingly, the air core correctors (1C04V at least) are not responding. The set points change, but the readbacks do not (Figure 3).
