QUICK SUMMARY: JAC output alignment continues in HAM1 today, and the HAM7 door is on and will start pumping down soon.

The PSL FSS had been searching for resonance with the autolocker on all night with no success, so I turned it off for now. I imagine the PZT ramp frequency was manually changed yesterday for JAC work and just was not reverted, so the autolocker wouldn't work.
