Observing 2057 UTC
Back to observing at 2057UTC.
Maintenance recovery was slowed by ITMY CPS glitching (alog72683) that Jim fixed by replacing a CPS card. This was also the cause of some lock losses last night.
We've had ITMY ST2 trip two more times since observing, but we haven't broken lock. Jim is preparing a new CPS card, but we'll have to break lock to do it if we choose to.
Intentionally broke to lock to fix allow for a fix of the CPS glitching. Relocking now.
