keyword=[target] Nose levelWent to Man Mode to control nose level at~16:30. Level fluctuations change polarization by 1-2% which makes it difficult to adjust microwave freq.
It looks like level probe fails to read out if the level in the nose drops below ~62%.
Seems 0.62 value for the Run Valve kept it stable at ~66% for ~1.5 hour (no beam trips)
