keyword=BPMA Y Position DriftedAt 8:38, the BPMA Y position drifted from 0.7 mm up to 1.6 mm. When
I talked with MCC, they said that the orbit locks were off when they
came on shift. This apparently caused the drift to occur.
Unfortunately, MCC misunderstood and also moved BPMB Y to 0.7 mm as
well.
This position drift affects run numbers: 2896, 2897 and 2898. The
position was corrected during run 2898 at about 9:08 am.
