Started all Separator Pass 5 (H)cavities to prepare for pass 5 horizontal separation. Initially had issues with cavity 5-2 (see Fig)
Started it to ~2.4 kw in tone mode and then switched it to GDR. Then turned of the RF and restarted it automatically and it started with no issues.

Per Riad, I'm OPS-PRing this issue to ourselves so we can keep track of it.

Sometime between yesterday morning and this morning, the C laser attenuator stage reference coordinate slipped by 100 units undetected; no difference between setpoint and readback, but the physical position was wrong. Homing resolved it. This is different than previous cases where Ops performed a home/reset to remove minor (< 1 unit) deviations between setpoint and readback.

As long as we don't know if this is a one-time or recurring issue, keep an eye on it and check laser power vs.
