H1 Back to Observing
H1 is now back to observing as of 00:09 UTC following input alignment changes and other maintenance today.
After we reached low noise, I took 10 minutes of no-SQZ time from 23:55 to 00:05 UTC.
I put together a quick DARM comparison of towards the end of the no-SQZ time mentioned above to now (~20 minutes later w/ SQZ). The low frequency noice bewteen roughly 18-100Hz does seem to be worse with SQZ injected versus not.
