Subject: drift in Y arm 

Why is the Y arm drifting so much?

The " PSL FSS Slow Actuator Adjust " was brought back to range from 1.5 to 0.3 yesterday as ususual. Nothing else was touched.

I'm not sure if the timing scale is working correctly on theses summery plots. What is the definition of today?

The y-arm became much better as I noticed it at 5pm
