18:34 UTC Observing
ITMY mode5/6s damping didn't seem to be going well today, I've been monitoring it on DTT after seeing the tall line on DARM and the DCPD min/max plot looking flat. I've found some new settings that seem to be bringing it down, based on the long & short monitors and DTT but more testing is needed to confirm. The new settings are FM5 + FM6 + FM10 G= -0.01, removing FM8. (Tagging SUS, OPS). I've set the gain to 0 in lscparams but I have not loaded the VIOLIN_DAMPING guardian.

00:00 - 00:03 UTC we dropped observing as the SUS_PI guardian fought (successfully) PI 24 in the new "XTREME_PI_DAMPING" state
