Briefly in Observe, ring up problems again though
The IFO just got to NLN, so I switched to Observe. Shortly after, the ring EX ring up reappeared, so we have dropped out of Observe again, and are tuning some ASC to try to settly the IFO down.
Getting ready to go back into Observe, Jenne had me reduce the gains on PRC1 Y with a -20dB filter, and reduce the gains on DHARD P (from 10 to 7) and Y(from 15 to 10). The low frequency ground motion is coming up, so we may be getting an earthquake.
