XTREME_PI_DAMPING
18:30 UTC H1 dropped from Observing due to a PI ring up that caused the SUS_PI Guardian to envoke XTREME_PI_DAMPING.
The SUS_PI guardian did great work and Damped the PI 24 down in 2 minutes.
H1 returned back to Observing at 18:32 UTC.
This happened again at 18:36 UTC and we got back to Observing at 18:37 UTC
This happened again at 18:42 UTC and we returned to Observing at 18:44 UTC after once again XTREME_PI_DAMPING.
Another PI24 Ring up that took us in to Comissioning at 18:57 UTC
This time we will stay in comissioning for a few minutes so Sheila can pico ASC Pop QPDS.
I've also taken SQZ MAN to NO_SqUEEZING[7] and switched back to FREQ_DEP_SQZ[100] at 19:28 UTC.
Sheila & Matt are still Pico-ing.
